abstract = {Floods are among natural disasters which cause the largest damages worldwide each year, inducing fatalities of human lives, destruction of infrastructure and economical losses. Consequently, forecasting this type of events through hydro-meteorological models is still of great importance from a civil protection point of view since it allows to reduce hydrological risk by means of early warning systems. Nevertheless, hydrological model initialization in ungauged basins, where there is lack of direct measurements of meteorological information, is a known issue affecting the entire prediction chain. The present study evaluates the possibility of using forecasts provided by the meteorological model MOLOCH developed by CNR-ISAC forcing the FEST-WB hydrological model developed by Politecnico di Milano to perform discharge simulations assuming that the forecasting errors are negligible when using the first 24 h of time horizon. The study is carried out in the urban catchments of Milan city, the Seveso-Olona-Lambro (SOL) river basins, located in northern Italy. The main hydro-meteorological variables are analysed by comparing the spatialized and observed meteorological data, provided by an official regional network of weather stations plus a citizen scientists' contribution with the meteorological model forecasts. Moreover, a sensitivity analysis following the well-known one-factor-at-a-time methodology is accomplished with the aim of defining which atmospheric forcing, beyond rainfall, mostly affects flowrate forecasts. Results generally show satisfactory correspondences between forecasts and observed data for the discharge variable at daily scale, although an underestimation of precipitation, particularly for severe events in summer, is present. Therefore, using meteorological forecasts to create daily initial conditions for hydrological model, instead of ground observations, might be a reliable and valuable approach, even if some considerations should be borne in mind when coupling the two models. © 2023 The Authors.

This study introduces a novel approach that combines the continuous slope-area method with LiDAR-derived vegetation data and water depths measured with piezoresistive sensors to evaluate floodplain discharges while considering variations in roughness coefficients induced by arboreal vegetation. We apply this approach to a specific reach of the Piave River in Italy using data collected during the December 2020 flood event. The study demonstrates the capability of the employed measurement system to record extreme floods and emphasizes the importance of including vegetation roughness variations in floodplain discharge calculations. The proposed approach has the potential to be applied in similar scenarios, providing valuable insights for floodplain discharge estimation in vegetated areas. © 2023 by the authors.},

ABSTRACT = {In this paper, the FEST-FOREST model is presented. A FOREST module is written in the FORTRAN-90 programming language, and was included in the FEST-WB distributed hydrological model delivering the FEST-FOREST model. FEST-FOREST is a process-based dynamic model allowing the simulation at daily basis of gross primary production (GPP) and net primary production (NPP) together with the carbon allocation of a homogeneous population of trees (same age, same species). The model was implemented based on different equations from literature, commonly used in Eco-hydrological models. This model was developed within the framework of the INNOMED project co-funded under the ERA-NET WaterWorks2015 Call of the European Commission. The aim behind the implementation of the model was to simulate in a simplified mode the forest growth under different climate change and management scenarios, together with the impact on the water balance at the catchment. On a first application of the model, the results are considered very promising when compared to field measured data.},

ABSTRACT = {The time of concentration is a fundamental parameter used for hydrological analysis
in professional and scientific communities. The availability of equations for its estimation
leads to significant variability and uncertainty. In this work, the most commonly used 24 equations
were selected among the empirically based models to compare their estimates and to quantify
the accuracy in predicting the time of concentration observed from 46 river basins in northern Italy.
The practical definition for direct time of concentration estimation used in this work computes it
as the time from the end of effective rainfall to the end of direct runoff on the recession limb
of the total hydrograph. The results show a large discrepancy between the observed values and those
estimated with the selected equations: the best performances are achieved by Bransby-Williams, Giandotti,
Soil Conservation Service, Témez, and Ferro equations. The catchment classification into classes of basins
with homogeneous climatological and physiographic characteristics shows that none of the analyzed
equations significantly improves the predictions. Finally, a new equation is proposed for the area
of the Upper Po River Basin that can significantly decrease the time-of-concentration estimation error.},

ABSTRACT = {Leachate production and management are recognized as one of the greatest problems associated with environmentally operations
for landfills. Variations in leachate quality and quantity are related to rainfall depth and its infiltration processes into landfill.
This work examines important hydrological problems of the Scarpino site (Genoa, northern Italy), a garbage dump which covers
the valley of a first order flash creek with a surface of 100 hectares, located in one of the rainiest area of Italy. The landfill is one
of the largest in Europe and it operates since the Sixties collecting waste at a rate of about 1000 tons per day. Its present structure
shows several horizontal layers of waste deposit separated by covers of compacted soil for a depth ranging from 40 to 70 meters.
The landfill surface is subdivided in zones delimited by artificial slopes.
The hydrology of the landfill is analyzed with a real time monitoring system which has been set up in order to manage and control
leachate fluxes and landfill slope stability acquiring: (i) meteorological variables, (ii) soil moisture profiles, (iii) leachate levels
inside the landfill body, (iv) discharge measurements of surface runoff basin and drained leachate at the landfill outlet, and (v)
leachate levels inside the storage tanks. Although it was a preliminary development state, this monitoring system was able to
provide the necessary information in order to evaluate the overall landfill hydrological response, particularly focused on the leachate
volume production.},

ABSTRACT = {The uncertainty in a hydrological model, due to its structure
or implemented input parameters, affects the accuracy of simulations that
are usually used for important applications such as drought predictions,
flood risk assessment, irrigation scheduling, ground water recharge and
contamination. Several models describing soil infiltration processes have
been developed. Some are analytical, while others implement numerical
solutions of the Richards' equation. The objective of this work was to
assess the impact of infiltration process modeling on soil water content
simulations. For this study, different infiltration models were included
within FEST-WB (Flash Flood Event-based Spatially-distributed rainfall-runoff
Transformations-Water Balance) distributed hydrological model (SCS-CN, Green and Ampt,
Philip and Ross solution). Performances of implemented infiltration models in
simulating soil water content were evaluated against observations acquired in
the experimental site located in a maize field in northern Italy. Soil water
content was monitored together with continuous measurements of meteorological data.
A sensitivity analysis was performed to assess the most important parameters
governing infiltration process in the different models tested. A comparison
of soil water content simulations show that Ross solution allowed the
description of soil moisture variation along the vertical, but simpler
lumped models provide sufficient accuracy when properly calibrated},

ABSTRACT = {The number of natural catastrophes that affect people worldwide
is increasing; among these, the hydro-meteorological events represent the
worst scenario due to the thousands of deaths and huge damages to private
and state ownership they can cause. To prevent this, besides various
structural measures, many non-structural solutions, such as the implementation
of flood warning systems, have been proposed in recent years.
In this study, we suggest a low computational cost method to produce
a probabilistic flood prediction system using a single forecast
precipitation scenario perturbed via a spatial shift. In fact, it is well-known
that accurate forecasts of heavy precipitation, especially associated with deep
moist convection, are challenging due to uncertainties arising from the numerical
weather prediction (NWP), and high sensitivity to misrepresentation of the initial
atmospheric state. Inaccuracies in precipitation forecasts are partially due
to spatial misplacing. To produce hydro-meteorological simulations and forecasts,
we use a flood forecasting system which comprises the physically-based
rainfall-runoff hydrological model FEST-WB developed by the Politecnico di Milano,
and the MOLOCH meteorological model provided by the Institute of
Atmospheric Sciences and Climate (CNR-ISAC). The areas of study are
the hydrological basins of the rivers Seveso, Olona, and Lambro located in
the northern part of Milan city (northern Italy) where this system works every
day in real-time. In this paper, we show the performance of reforecasts carried
out between the years 2012 and 2015: in particular, we explore the ‘Shift-Target’ (ST)
approach in order to obtain 40 ensemble members, which we assume equally likely,
derived from the available deterministic precipitation forecast. Performances are
shown through statistical indexes based on exceeding the threshold for different
gauge stations over the three hydrological basins. Results highlight how the Shift-Target
approach complements the deterministic MOLOCH-based flood forecast for warning purposes},

water movement from soil surface to groundwater and to predict onset of stress
conditions within agricultural fields. However, optimal use of mathematical
models requires intensive, time consuming and expensive collection of soil
related parameters. Typically soils to be characterized exhibit large variations
in space and time as well during the cropping cycle, due to biological processes
and agricultural management practices: tillage, irrigation, fertilization and harvest.
This paper investigates the variability of soil hydraulic properties over a cropping
cycle between April and September 2015, within a surface irrigated maize field (6 ha)
located in northern Italy. To this aim, undisturbed and disturbed soil samples were
collected from different locations within the study area and at different depths,
during three measuring campaigns, at the beginning, in the middle of the cropping
season and after the harvest. For each soil sample, several parameters were monitored:
organic matter and bulk density together with soil hydraulic parameters.
Soil parameters of Soil water retention curve parameters were measured following
the evaporation method, while the saturated hydraulic conductivity was determined
in the laboratory using the well-known falling head method. Results show that soil
properties, mainly the saturated hydraulic conductivity, are subjected to
significant variations. The variability of these parameters was taken into
consideration when simulating soil moisture using FEST-WB model.
An improvement in soil water content simulations was observed as compared
to field measurements with implications on prediction of water stress
conditions that is fundamental for irrigation scheduling},

ABSTRACT = {Two-dimensional hydraulic modeling is fundamental to simulate flood
events in urban area. Key factors to reach optimal results are detailed information
about domain geometry and utility of hydrodynamic models to integrate the full or
simplified Saint Venant equations in complex geometry. However, in some cases,
detailed topographic datasets that represent the domain geometry are not available,
so approximations—such as diffusive wave equation—is introduced whilst representing
urban area with an adjusted roughness coefficient. In the present paper, different
methods to represent buildings and approximation of the Saint Venant equations are
tested by performing experiments on a scale physical model of urban district in laboratory.
Simplified methods are tested for simulation of a real flood event which occurred in 2013
in the city of Olbia, Italy. Results show that accuracy of simulating flow depth with a
detailed geometry is comparable to the one achieved with an adjusted roughness coefficient.},

ABSTRACT = {The Food and Agricultural Organization (FAO) method for potential evapotranspiration
assessment is based on the crop coefficient, which allows one to relate the reference evapotranspiration
of well irrigated grass to the potential evapotranspiration of specific crops. The method was originally
developed for cultivated species based on lysimeter measurements of potential evapotranspiration.
Not many applications to natural vegetated areas exist due to the lack of available data for these
species. In this paper we investigate the potential of using evapotranspiration measurements acquired
by micrometeorological stations for the definition of crop coefficient functions of natural vegetated
areas and extrapolation to ungauged sites through remotely sensed data. Pastures, deciduous and
evergreen forests have been considered and lower crop coefficient values are found with respect to
FAO data.},

ABSTRACT = {Increased water demand and climate change impacts have recently enhanced the need to improve
water resources management, even in those areas which traditionally have an abundant supply of
water, such as the Po Valley in northern Italy. The highest consumption of water is devoted to
irrigation for agricultural production, and so it is in this area that efforts have to be focused to study
possible interventions. Meeting and optimizing the consumption of water for irrigation also means
making more resources available for drinking water and industrial use, and maintaining an optimal
state of the environment. In this study we show the effectiveness of the combined use of numerical
weather predictions and hydrological modelling to forecast soil moisture and crop water requirement
in order to optimize irrigation scheduling. This system combines state of the art mathematical
models and new technologies for environmental monitoring, merging ground observed data with
Earth observations from space and unconventional information from the cyberspace through
crowdsourcing.},

ABSTRACT = {On 12 October 2007, several flash floods affected the
Valencia region, eastern Spain, with devastating impacts in terms
of human, social, and economic losses. An enhanced modeling
and forecasting of these extremes, which can provide a tangible
basis for flood early warning procedures and mitigation measures
over the Mediterranean, is one of the fundamental motivations of
the international Hydrological Cycle in the Mediterranean
Experiment (HyMeX) program. The predictability bounds set by
multiple sources of hydrological and meteorological uncertainty
require their explicit representation in hydrometeorological
forecasting systems. By including local convective precipitation
systems, short-range ensemble prediction systems (SREPSs) provide
a state-of-the-art framework to generate quantitative discharge
forecasts and to cope with different sources of external-scale
(i.e., external to the hydrological system) uncertainties.
The performance of three distinct hydrological ensemble
prediction systems (HEPSs) for the small-sized Serpis River
basin is examined as a support tool for early warning and
mitigation strategies. To this end, the Flash-Flood Event–Based
Spatially Distributed Rainfall–Runoff Transformation–Water Balance
(FEST-WB) model is driven by ground stations to examine the
hydrological response of this semiarid and karstic catchment
to heavy rains. The use of a multisite and novel calibration
approach for the FEST-WB parameters is necessary to cope with
the high nonlinearities emerging from the rainfall–runoff
transformation and heterogeneities in the basin response.
After calibration, FEST-WB reproduces with remarkable accuracy
the hydrological response to intense precipitation and,
in particular, the 12 October 2007 flash flood.
Next, the flood predictability challenge is focused on
quantitative precipitation forecasts (QPFs).
In this regard, three SREPS generation strategies using
the WRF Model are analyzed. On the one side, two SREPSs
accounting for 1) uncertainties in the initial conditions (ICs)
and lateral boundary conditions (LBCs) and 2) physical parameterizations
are evaluated. An ensemble Kalman filter (EnKF) is also designed to
test the ability of ensemble data assimilation methods to represent
key mesoscale uncertainties from both IC and subscale processes.
Results indicate that accounting for diversity in the physical
parameterization schemes provides the best probabilistic high-resolution
QPFs for this particular flash flood event. For low to moderate
precipitation rates, EnKF and pure multiple physics approaches
render undistinguishable accuracy for the test situation at larger scales.
However, only the multiple physics QPFs properly drive the HEPS to render
the most accurate flood warning signals. That is, extreme precipitation
values produced by these convective-scale precipitation systems anchored
by complex orography are better forecast when accounting just for
uncertainties in the physical parameterizations. These findings contribute
to the identification of ensemble strategies better targeted to the most
relevant sources of uncertainty before flash flood situations over small catchments.},

accuracy comparable to TDR in estimating water content,
with DPHP showing lower values of error index in 3 samples
out of 4. The DPHP can be used to investigate smaller volume
of soil than TDR probe can do however, TDR is much faster

ABSTRACT = {Analysis of ensemble forecasting strategies, which can provide a
tangible backing for flood early warning procedures and mitigation measures
over the Mediterranean region, is one of the fundamental motivations of the
international HyMeX programme. Here, we examine two severe hydrometeorological
episodes that affected the Milano urban area and for which the complex flood
protection system of the city did not completely succeed. Indeed, flood damage
have exponentially increased during the last 60 years, due to industrial and
urban developments. Thus, the improvement of the Milano flood control system
needs a synergism between structural and non-structural approaches.
First, we examine how land-use changes due to urban development have altered
the hydrological response to intense rainfalls. Second, we test a flood
forecasting system which comprises the Flash-flood Event-based Spatially
distributed rainfall–runoff Transformation, including Water Balance (FEST-WB)
and the Weather Research and Forecasting (WRF) models. Accurate forecasts of
deep moist convection and extreme precipitation are difficult to be predicted
due to uncertainties arising from the numeric weather prediction (NWP) physical
parameterizations and high sensitivity to misrepresentation of the atmospheric state;
however, two hydrological ensemble prediction systems (HEPS) have been designed to
explicitly cope with uncertainties in the initial and lateral boundary conditions
(IC/LBCs) and physical parameterizations of the NWP model. No substantial differences
in skill have been found between both ensemble strategies when considering an
enhanced diversity of IC/LBCs for the perturbed initial conditions ensemble.
Furthermore, no additional benefits have been found by considering more frequent
LBCs in a mixed physics ensemble, as ensemble spread seems to be reduced.
These findings could help to design the most appropriate ensemble strategies
before these hydrometeorological extremes, given the computational cost of
running such advanced HEPSs for operational purposes.},

climate models simulate an increase of mean annual precipitation distributed over spring, autumn

ABSTRACT = {This study addresses the estimation of flow-duration curves (FDC) in ungauged sites through the catchment classification.
Forty-six catchments in the Upper Po river basin (Italy) were analyzed and classified through two different frameworks: the first scheme
consists of the application of two clustering methods in a series considering six streamflow signatures, and the second one treats indexes of
climate, physiography, soil, and land-use with the same clustering procedure. Catchments have been classified into three homogeneous
groups: the first one is characterized by the lowest runoff and flash-flood events, the second one includes maximum runoff, and the third
one shows intermediate behaviour. The estimation of FDCs was done using a lognormal distribution, whereas the regionalization was
constructed applying a stepwise multiple linear regression, followed by a leave-one-out cross-validation. The results show great performance
improvement when the regionalization model is found by taking account of the three different hydrological classes, with a mean absolute
percentage error that decreases from 11% for the single region case to 7% in the three homogeneous regions case},

ABSTRACT = {Climate change can have profound impacts on water availability.
In order to assess the impacts on water resources in complex
Alpine river basins, an integrated model that can simulate mutual
interactions between natural hydrological processes and
anthropogenic disturbances is required. The objective of this
study is to show the potential of such an integrated approach
in quantifying the impacts of climate change on water
resources availability in the Upper Po river basin in Italy.
Results show that in the time slice 2041–2050 summer river
discharge is expected to decrease with respect to 2001–2010,
due to a substantial decrease of seasonal precipitation and
an accelerated snow melt that causes an earlier snow depletion.
Glaciers volume is expected to decrease to half the current
value in 2025, while the minimum elevation of the lowest point
of the glaciers is expected to increase from 1890 m asl to
about 2850 m asl. It is shown that this change can affect
regulation of large artificial reservoirs at higher
elevation that are mainly dependent on glacier melt
for their supply. Increase of annual precipitation is
expected to increase groundwater detention that can be
used as supplement to diminished river discharge during summer.},

ABSTRACT = {Flood frequency estimation is crucial in both engineering practice and hydrological research. Regional
analysis of flood peak discharges is used for more accurate estimates of flood quantiles in ungauged or poorly
gauged catchments. This is based on the identification of homogeneous zones, where the probability distribution
of annual maximum peak flows is invariant, except for a scale factor represented by an index flood. The
numerous applications of this method have highlighted obtaining accurate estimates of index flood as a critical
step, especially in ungauged or poorly gauged sections, where direct estimation by sample mean of annual flood
series ({AFS}) is not possible, or inaccurate. Therein indirect methods have to be used. Most indirect methods are
based upon empirical relationships that link index flood to hydrological, climatological and morphological
catchment characteristics, developed by means of multi-regression analysis, or simplified lumped representation
of rainfall–runoff processes. The limits of these approaches are increasingly evident as the size and spatial
variability of the catchment increases. In these cases, the use of a spatially-distributed, physically-based hydrological
model, and time continuous simulation of discharge can improve estimation of the index flood. This work
presents an application of the FEST-WB model for the reconstruction of 29 years of hourly streamflows for an
Alpine snow-fed catchment in northern Italy, to be used for index flood estimation. To extend the length of the
simulated discharge time series, meteorological forcings given by daily precipitation and temperature at ground
automatic weather stations are disaggregated hourly, and then fed to {FEST-WB}. The accuracy of the method in
estimating index flood depending upon length of the simulated series is discussed, and suggestions for use of the
methodology provided.},

ABSTRACT = {In recent years frequent periods of water scarcity
have enhanced the need to use water more carefully, even
in European areas which traditionally have an abundant supply
of water, such as the Po Valley in northern Italy. In dry
periods, water shortage problems can be enhanced by conflicting
uses of water, such as irrigation, industry and power
production (hydroelectric and thermoelectric). Furthermore,
in the last decade the social perspective in relation to this issue
has been increasing due to the possible impact of climate
change and global warming scenarios which emerge from the
IPCC Fifth Assessment Report (IPCC, 2013). Hence, the increased
frequency of drought periods has stimulated the improvement
of irrigation and water management.
In this study we show the development and implementation
of the PREGI real-time drought forecasting system;
PREGI is an Italian acronym that means “hydrometeorological
forecast for irrigation management”. The system,
planned as a tool for irrigation optimization, is based on
meteorological ensemble forecasts (20 members) at medium
range (30 days) coupled with hydrological simulations of water
balance to forecast the soil water content on a maize field
in the Muzza Bassa Lodigiana (MBL) consortium in northern
Italy. The hydrological model was validated against measurements
of latent heat flux acquired by an eddy-covariance
station, and soil moisture measured by TDR (time domain
reflectivity) probes; the reliability of this forecasting system
and its benefits were assessed in the 2012 growing season.
The results obtained show how the proposed drought forecasting
system is able to have a high reliability of forecast at
least for 7–10 days ahead of time.},

ABSTRACT = {Assessing the future effects of climate change on
water availability requires an understanding of how precipitation and
evapotranspiration rates will respond to changes in atmospheric forcing.
Use of simplified hydrological models is required
beacause of lack of meteorological forcings with the high space and time
resolutions required to model hydrological
processes in mountains river basins, and the necessity of reducing
the computational costs. The main objective of this study
was to quantify the differences between a simplified hydrological model,
which uses only precipitation and temperature to
compute the hydrological balance when simulating the impact of
climate change, and an enhanced version of the model,
which solves the energy balance to compute the actual
evapotranspiration. For the meteorological forcing of future
scenario, at-site bias-corrected time series based on two
regional climate models were used. A quantile-based error correction
approach was used to downscale the regional climate model
simulations to a point scale and to reduce its error
characteristics. The study shows that a simple
temperature-based approach for computing the evapotranspiration is
sufficiently accurate for performing hydrological impact
investigations of climate change for the Alpine river basin which
was studied.},

ABSTRACT = {Observed climate change has already led to a wide range of impacts on environmental systems and society. In this
context, many mountain regions seem to be particularly sensitive to a changing climate, through increases in
temperature coupled with changes in precipitation regimes that are often larger than the global average (EEA,
2012). In mid-latitude mountains, these driving factors strongly influence the variability of the mountain
snow-pack, through a decrease in seasonal reserves and earlier melting of the snow pack. These in turn impact
on hydrological systems in different watersheds and, ultimately, have consequences for water management.
Snow monitoring from remote sensing provides a unique opportunity to address the question of snow cover
regime changes at the regional scale. This study outlines the results retrieved from the MODIS satellite images
over a time period of 10 hydrological years (2000–2010) and applied to two case studies of the EU FP7
ACQWA project, namely the upper Rhone and Po in Europe and the headwaters of the Syr Darya in Kyrgyzstan
(Central Asia). The satellite data were provided by the MODIS Terra MOD-09 reflectance images (NASA) and
MOD-10 snow products (NSIDC). Daily snow maps were retrieved over that decade and the results presented
here focus on the temporal and spatial changes in snow cover. This paper highlights the statistical bias observed
in some specific regions, expressed by the standard deviation values (STD) of annual snow duration. This bias is
linked to the response of snow cover to changes in elevation and can be used as a signal of strong instability in
regions sensitive to climate change: with alternations of heavy snowfalls and rapid snow melting processes.
The interest of the study is to compare the methodology between the medium scales (Europe) and the large
scales (Central Asia) in order to overcome the limits of the applied methodologies and to improve their performances.
Results show that the yearly snow cover duration increases by 4–5 days per 100 m elevation during
the accumulation period, depending of the watershed, while during the melting season the snow depletion
rate is 0.3% per day of surface loss for the upper Rhone catchment, 0.4%/day for the Syr Darya headwater basins,
and 0.6%/day for the upper Po, respectively. Then, the annual STD maps of snow cover indicate higher values
(more than 45 days difference compared to the mean values) for (i) the Po foothill region at medium elevation
(SE orientation) and (ii) the Kyrgyzstan high plateaux (permafrost areas). These observations cover only a timeperiod
of 10 years, but exhibit a signal under current climate that is already consistentwith the expected decline
in snow in these regions in the course of the 21st century.},

ABSTRACT = {It is widely recognized that urban development alters infiltration capacity and
enhances its spatial variability, but also constrains watercourses into narrow channels making
them unable to contain the runoff that is generated by relatively small, but intense, rainfall
events. Network of detention basins are designed to reduce the flood peak by temporarily
storing the excess storm water and then releasing the water volume at allowable rates over an
extended period. This paper shows the use of a distributed hydrological model for the
assessment of effectiveness of a network of detention facilities in a heavily urbanized river
basin. The distributed hydrological model FEST was used to assess design hydrograph and, in
parallel to design the seven detention basins optimized for the specific purpose of maintaining
the flow rate within the range of the maximum allowable discharge. This permitted to estimate
the design hydrograph considering both the spatial variability of soil infiltration capacity and
routing characteristics induced by each detention basins along the main river. Results indicate
that on-stream detention ponds can increase duration of the critical event and runoff volume of
design flood with possible negative implications on downstream facilities.},

ABSTRACT = {A raster-based glacier sub-model was successfully introduced in the distributed hydrological model FEST-WB to simulate the
water balance and surface runoff of large Alpine catchments. The glacier model is based on temperature-index approach for melt,
on linear reservoir for melt water propagation into the ice and on mass balance for accumulation; the initialization of the volume
of ice on the basin was based on a formulation depending on surface topography. The model was first tested on a sub-basin of the
Rhone basin (Switzerland), which is for 62% glaciated; the calibration and validation were based on comparison between
simulated and observed discharge from 1999 to 2008. The model proved to be suitable to simulate the typical discharge
seasonality of a heavily glaciated basin. The performance of the model was also tested by simulating discharge in the whole
Swiss Rhone basin, in which glaciers contribution is not negligible, in fact, in summer, about the 40% of the discharge is due to
glacier melt. The model allowed to take into account the volume of water coming from glaciers melt and its simple structure is
suitable for analysis of the effects of climate change on hydrological regime of high mountain basins, with available
meteorological forcing from current RCM.},

ABSTRACT = {A method for indirect estimation of design flood in poorly gauged urbanized river basins by using distributed hydrological
modelling is presented. It is based on the critical flood design criterion that maximizes peak flow for a given return period by transforming
precipitation of depth duration frequency curve into runoff. The indirect method is compared against the direct method based on regional
approach and index flood estimation. This paper shows that the direct method significantly underestimates design flood in case discharge
measurements are strongly affected by artificial alteration of water courses with possible catastrophic consequences in terms of loss of life and
damage to property when the cause of alteration would be removed. Moreover, the use of a spatially distributed model allows taking into
account the heterogeneity that generally characterizes river basins with an high degree of urbanization. The presented indirect method provides
a design hydrograph that is useful for those cases in which design discharge only is not sufficient for designing or planning purposes.},

ABSTRACT = {In recent years the interest in the forecast and prevention
of natural hazards related to hydro-meteorological
events has increased the challenge for numerical weather
modelling, in particular for limited area models, to improve
the quantitative precipitation forecasts (QPF) for hydrological
purposes.
After the encouraging results obtained in the MAP DPHASE
Project, we decided to devote further analyses to
show recent improvements in the operational use of hydrometeorological
chains, and above all to better investigate the
key role played by temperature during snowy precipitation.
In this study we present a reanalysis simulation of one meteorological
event, which occurred in November 2008 in the
Piedmont Region. The attention is focused on the key role
of air temperature, which is a crucial feature in determining
the partitioning of precipitation in solid and liquid phase, influencing
the quantitative discharge forecast (QDF) into the
Alpine region. This is linked to the basin ipsographic curve
and therefore by the total contributing area related to the
snow line of the event.
In order to assess hydrological predictions affected by meteorological
forcing, a sensitivity analysis of the model output
was carried out to evaluate different simulation scenarios,
considering the forecast effects which can radically modify
the discharge forecast.
Results show how in real-time systems hydrological forecasters
have to consider also the temperature uncertainty in
forecasts in order to better understand the snow dynamics
and its effect on runoff during a meteorological warning with
a crucial snow line over the basin.
The hydrological ensemble forecasts are based on
the 16 members of the meteorological ensemble system
COSMO-LEPS (developed by ARPA-SIMC) based on the
non-hydrostatic model COSMO, while the hydrological
model used to generate the runoff simulations is the rainfall–
runoff distributed FEST-WB model, developed at Politecnico
di Milano.},

parameter starting from information about soil type and usage and we let calibration change only the mean value,
through a correction factor. The study area in which this methodology has been applied is Piemonte, with a total of 50
flow measurements series. With this large amount of discharge data it is possible to test a multi-site calibration
approach. The results show that the use of only one measure for calibration highlight some shortcomings in the
validation results, while the use of all the measures together improve model performance in all catchments levels.},

ABSTRACT = {In recent years frequent periods of water scarcity have enhanced the need to use water more carefully, even in
European areas traditionally rich of water such as the Po Valley in northern Italy. In dry periods the problem of water
shortage can be enhanced by conflictual use of water such as irrigation, industrial and power production
(hydroelectric and thermoelectric). Further, over the last decade the social perspective on this issue is increasing due
to possible impacts of climate change and global warming scenarios which come out from the last IPCC Report. The
increased frequency of drought periods has stimulated the improvement of irrigation and water management.
In this study we show the development and implementation of the real-time drought forecasting system Pre.G.I., an
Italian acronym that stands for “Hydro-Meteorological forecast for irrigation management”.
The system is based on ensemble prediction at long range (30 days) with hydrological simulation of water balance to
forecast the soil water content in field parcels over the Consorzio Muzza basin. The studied area covers 74,000 ha in
the middle of the Po Valley, near the city of Lodi.
The hydrological ensemble forecasts are based on 20 meteorological members of the non-hydrostatic WRF-ARW
model with 30 days as lead-time, provided by Epson Meteo Centre, while the hydrological model used to generate
soil moisture simulations is the rainfall-runoff distributed FEST-WB model, developed at Politecnico di Milano.
The hydrological model was validated against measurements of latent heat flux and soil moisture acquired by an
eddy-covariance statio*n. Reliability of the forecasting system and its benefits was assessed on some cases-study
occurred in the growing season of 2012.},

ABSTRACT = {Deriving accurate estimates of reference evapotranspiration is required for water resource management, irrigation water requirement
computations, and successful hydrological modeling. The Food and Agricultural Organization of the United Nations (FAO) recommended
the Penman-Monteith equation as the standard for estimating reference evapotranspiration. An alternative method for application at
sites where only air temperature measurements are available is the Hargreaves-Samani equation. The primary objective of this study is to
investigate the possibility for application of the Hargreaves-Samani equation in alpine areas for computing daily reference evapotranspiration.
An evaluation of the Hargreaves-Samani equation and its modifications proposed in literature is made by comparing daily estimates with
Penman-Monteith results at 51 meteorological stations in the Upper Po River Basin (Italy) and the Rhone River Basin (Switzerland). Significant
error was encountered in all methods using the Hargreaves-Samani equation. A relationship for adjusting the Hargreaves-Samani
coefficient on the basis of local elevation is proposed, calibrated, and validated. The resulting modified Hargreaves-Samani equation showed a
significant reduction of error for estimating daily reference evapotranspiration. The proposed equation is not intended for replacement of the
Penman-Monteith method but for application in alpine rivers when only air temperature data are available.},

ABSTRACT = {The atmospheric turbulence in the planetary boundary layer (PBL)
governs the mass and energy exchange over the soil-vegetation-atmosphere system.
Micrometeorological stations based on the eddy-covariance technique have been
recently developed for the assessment of latent and sensible heat fluxes through
high frequency measurements of the fluctuating component of wind velocity,
temperature and air water content in the PBL. Correct interpretation of such
measurements requires assessment of the actual source area (footprint)
contributing to the eddy fluxes (latent and sensible heat). Many different
approaches have been developed to estimate the source area function but there
is no general consensus on the accuracy and applicability of these methods.
The objective of this work is to demonstrate the existence of a relationship
between the representative source area for eddy covariance measurements,
and the large eddies responsible for the transport of turbulent
kinetic energy (TKE). Moreover, the energy balance closure was used
to analyze the possible effects of the different lengths of the source
area on the heat fluxes. A series of measurements were carried out in a
micrometeorological eddy covariance station located in a maize field in
Landriano in Po Valley (PV), Italy. The results show that the dimension
of the large eddies is tightly bound to the footprint size, leading},

for a synergic use of hydrological model with remote sensing data.
In particular, the energy budget is solved looking for the representative
thermodynamic equilibrium temperature (RET) defined as the land surface
temperature (LST) that closes the energy balance equation for any
pixel of basin surface. So using this approach, through the system
between the mass and energy equations, soil moisture (SM) is linked
to the latent heat flux (LE) and then to LST. The RET thermodynamic
approach solves most of the problems of the actual evapotranspiration
(ET) and SM computation. In fact, it permits to avoid computing the
effective ET as an empirical fraction of the potential one. This
approach, based on the RET, has been tested at field scale (10 ha)
with energy fluxes and LST measured with an eddy covariance station
in Landriano (Italy)},

of climate change, and increasingly stringent water management regulations

mitigate water shortage, it was recently proposed to use the water
stored into numerous quarries of gravel material. Because quarry

drawdown induced by pumping can affect flow in nearby streams.
The evaluation of the potential of quarry lakes for supplemental irrigation
has to face stream depletion that is crucial from the perspective
of the legal rights of the downstream users and ecosystem sustainability.
The work presented in this paper investigates the potential of a
quarry lake in Padana Valley to sustain irrigated crop water requirement
during shortage periods. A simple and quite inexpensive technique
for assessing streambed conductance based on streambed temperature
measurements is presented. The results show that quarry lakes may
be a promising alternative resource for supplemental irrigation during

abstract = {The Soil Conservation Service-curve number (SCS-CN) method is widely
used in hydrologic practice, but its application often goes beyond
the purpose of its original use. Common practice makes the method
dependent on the antecedent precipitation index, a simple indicator
derived from rainfall depth, which can be used to estimate the antecedent
moisture condition (AMC) of soil. By taking data from an unspecified
location in the United States, the SCS defined the appropriate AMC
level based on the total five-day antecedent rainfall for dormant
and growing seasons. These values, originally defined as an example
practice at the plot scale, were subsequently adopted for general
use without full awareness of scale effects and regional differences.
We propose a revision to the amount of antecedent rainfall for the
definition of AMC of soil, based on the minimization of the errors
between an estimated and an observed runoff volume of 347 rainfall-runoff
events in large mountain basins in Italy and Switzerland. A significant
correlation between the new thresholds and the topographic index
is shown, thus permitting extension of the method to basins not included

abstract = {Definition of flood risk maps is a task to which modern surface hydrology
devotes substantial research effort. Their
impact on the management of flood-prone, dense, urban areas has increased
the need for better investigation of
inundation dynamics. The problems associated with the aforementioned
topics range from the definition of the
design hydrograph and the identification of the surface boundary conditions
for the flood routing over the
inundation plan, to the choice of the hydrodynamic model to simulate
urban flooding. Most of academic and
commercial mathematical models, solving the De Saint Venant equations,
fail on complex topography. Frequently
encountered difficulties concern steep slopes, geometric discontinuities,
mixed flow regimes, and initially dry areas.
In the present paper, flood routing modelling approaches in urban
areas and principles for the definition of the
design flood events are outlined. The paper shows how urban flooding
can be simulated by a quasi-2D
hydrodynamic model that makes use of a network of connected channels
and storages to simulate flow, respectively,
on the streets and into the building blocks. Furthermore, the paper
shows that, when flood hazard is assessed by
considering flood extent, water depth and flow velocity, an in-depth
analysis of the use of design hydrographs that
maximise peak flow or inundation volume is needed.},

to Civil Protection services requires reliability and rapidity.
At present, computational capabilities overcome the rapidity needs even
when a fully distributed hydrological model is adopted for a large
river catchment as the Upper Po river basin closed at Ponte Becca
(nearly 40 000 km2). This approach allows simulating the whole domain
and obtaining the responses of large as well as of medium and little
sized sub-catchments. The FEST-WB hydrological model (Mancini, 1990;
Montaldo et al., 2007; Rabuffetti et al., 2008) is implemented. The
calibration and verification activities are based on more than 100
flood events, occurred along the main tributaries of the Po river in
the period 2000–2003. More than 300 meteorological stations are used
to obtain the forcing fields, 10 cross sections with continuous and
reliable discharge time series are used for calibration while
verification is performed on about 40 monitored cross sections.
Furthermore meteorological forecasting models are used to force
the hydrological model with Quantitative Precipitation Forecasts
(QPFs) for 36 h horizon in "operational setting" experiments.
Particular care is devoted to understanding how QPF affects the
accuracy of the Quantitative Discharge Forecasts (QDFs) and to
assessing the QDF uncertainty impact on the warning system reliability.
Results are presented either in terms of QDF and of warning issues
highlighting the importance of an "operational based" verification approach.},

abstract = {The most widely used method for snow dynamic simulation relies on
temperature index approach, that makes snow melt and accumulation
processes depend on air temperature related parameters. A recently
used approach to calibrate these parameters is to compare model results
with snow coverage retrieved from satellite images. In area with
complex topography and heterogeneous land cover, snow coverage may
be affected by the presence of shaded area or dense forest that make
pixels to be falsely classified as uncovered. These circumstances
may have, in turn, an influence on calibration of model parameters.
In this paper we propose a simple procedure to correct snow coverage
retrieved from satellite images. We show that using raw snow coverage
to calibrate snow model may lead to parameter values out of the range
accepted by literature, so that the timing of snow dynamics measured
at two ground stations is not correctly simulated. Moreover, when
the snow model is implemented into a continuous distributed hydrological
model, we show that calibration against corrected snow coverage reduces
the error in the simulation of river flow in an Alpine catchment.

abstract = {In recent years, the interest in the prediction and prevention of
natural hazards related to hydrometeorological events has grown due
to the increased frequency of extreme rainstorms. Several research
projects have been developed to test hydrometeorological models for
real-time flood forecasting. However, flood forecasting systems are
still not widespread in operational context. Real-world examples
are mainly dedicated to the use of flood routing model, best suited
for large river basins. For small basins, it is necessary to take
advantage of the lag time between the onset of a rainstorm and the
beginning of the hydrograph rise, with the use of rainfall-runoff
transformation models. Nevertheless, when the lag time is very short,
a rainfall predictor is required, as a result, meteorological models
are often coupled with hydrological simulation. While this chaining
allows floods to be forecasted on small catchments with response
times ranging from 6 to 12 hours it, however, causes new problems
for the reliability of Quantitative Precipitation Forecasts (QPF)
and also creates additional accuracy problems for space and time
scales.
The aim of this work is to evaluate the degree to which uncertain
QPF affects the reliability of the whole hydro-meteorological alert
system for small catchments. For this purpose, a distributed hydrological
model (FEST-WB) was developed and analysed in operational setting
experiments, i.e. the hydrological model was forced with rain observation
until the time of forecast and with the QPF for the successive period,
as is usual in real-time procedures. Analysis focuses on the AMPHORE
case studies in Piemonte in November 2002.},

abstract = {With the objective of improving flood predictions, in recent years
sophisticated continuous hydrologic models including complex land
surface sub-models have been developed. This has produced a significant
increase in parameterization; consequently, applications of distributed
models to ungaged basins lacking specific data from field campaigns
may become redundant.
The objective of this paper is to produce a parsimonious and robust
distributed hydrologic model for flood predictions in Italian Alpine
basins. Application is made to the Toce basin (area of 1534 km2).
The Toce basin was a case study of the RAPHAEL European Union research
project, during which a comprehensive set of hydrologic, meteorological
and physiographic data were collected, including the hydrologic analysis
of the 1996-1997 period. Two major floods occurred during this period.
We compare the FEST04 event model, which computes rainfall abstraction
and antecedent soil moisture conditions through the simple SCS-CN
method, and two continuous hydrologic models, SDM and TDM, which
differ in soil water balance scheme, and base flow and runoff generation
computations.
The simple FEST04 event model demonstrated good performance in the
prediction of the 1997 flood, but shows limits in the prediction
of the long and moderate 1996 flood. More robust predictions are
obtained with the parsimonious SDM continuous hydrologic model, which
uses a simple one-layer soil water balance model and an infiltration
excess mechanism for runoff generation, and demonstrates good performance
in both long-term runoff modeling and flood predictions. Instead,
the use of a more sophisticated continuous hydrologic model, the
TDM, that simulates soil moisture dynamics in two-layers of soil,
and computes runoff and base flow using some TOPMODEL concepts, does
not seem to be advantageous for this Alpine basin

abstract = {The rainfall threshold is the cumulated rainfall depth required to
cause flooding flow at the basin outlet. Thresholds are used in operational
flood forecasting systems as a means to provide flood warnings based
on the comparison with rainfall amounts (either observed or forecast).
This approach results in a simple system that can also be used by
non expert technicians; it is a complementary tool to "classical"
rainfall-runoff modelling systems. Despite the simple usage, a flood
forecasting system based on thresholds requires great accuracy in
definition of the critical rainfall. Special attention is required
in modelling the basin moisture condition. The aim of this paper
is to assess a reliability analysis of a framework for the definition
of rainfall thresholds using the distributed hydrological model FEST.
The AMC value (antecedent moisture condition) of the conventional
SCS-CN method is employed to describe the soil moisture initial condition.
The case study is the Arno River basin located in Italy. A detailed
investigation of the most recent flood events shows that precise
accounting of the watershed wetness based on analysis of actual soil
moisture can improve the prediction accuracy of flood forecasting
systems. },

Defi nition of fl ood risk maps is a task to which
modern surface hydrology addresses a substantial
research effort. Their impact on the government of
the fl ood prone areas have increased the need for
better investigation of the inundation dynamics
[Fema 2002]. This identifi es open research
problems such as: the defi nition of the design
hydrograph, the identifi cation of the surface
boundary conditions for the fl ood routing over
the inundation plan, the choice of the hydraulic
model that is the most close to the physical
behaviour of the fl ood routing in the specifi c
environment, such as urban areas or river valley.
Most of academic and commercial mathematical
models resolving the De Saint Venant equations
in mono or bidimensional approach, fail on
complex topography. Steep slopes, geometric
discontinuities, mixed fl ow regimes, initially dry
areas are just the main problems an hydraulic
model should solve. In this study, we address two
points: the defi nition of the critical event for an
inundation area and a fl ood routing modelling
technique for a highly urbanized fl at area. For this
latter we show that, in urban areas, a modelling
scheme of a network of connected channels
and storages, gives a better representation of
surface boundary conditions such as aggregation
of buildings and road network and suffi cient
accuracy for fl ood risk mapping purpose respect
