This work investigates the possibility of rehabilitating and using volumes made available by the creation of quarries of inert materials in watercourse flood plains for the regulation of floods and for the maintenance of supplies in times of water scarcity. Such activities offer technical and economic synergies between the need for production of in...

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 n...

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 wid...

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 c...

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...

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 des...

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 prod...

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, ...

The distributed event based hydrological model FEST, that adopts the classical SCS-CN method for abstractions, was extended for continuous simulation. The new FEST-WB model makes use of a simplified local water and energy balance scheme, accounting for soil, vegetation and atmosphere interactions, to provide Antecedent Moisture Condition (AMC) at r...

This study is part of the international MAP-D-PHASE Project, whose main objective is to demonstrate the benefits in forecasting heavy precipitation and related flood events, by coupling atmospheric and hydrological models. The analysis is focused on the River Toce, a middle-size alpine basin, in North-West of Italy. The hydro-meteorological chain i...

L’attività estrattiva nelle aree della pianura lombarda è un tipico esempio del conflitto fra attività produttiva e impatto sull’ambiente. Negli ultimi tempi la più diffusa sensibilità ambientale nonché le indicazioni delle direttive comunitarie sembrano avere acuito la conflittualità rendendo sempre più necessario l’inserimento nella...

Il sistema montuoso alpino è caratterizzato dalla presenza di numerosi laghi regolati sia di origine naturale che artificiale. Il loro ruolo risulta fondamentale per la riduzione della pericolosità delle piene fluviali e per la produzione di energia. I laghi alpini costituiscono, inoltre, una importante riserva idrica per il mantenimento del defl...

Definition of flood risk maps is a task to which modern surface hydrology addresses a substantial research effort. Their impact on the government of the flood prone areas have increased the need for better investigation of the inundation dynamics [Fema 2002]. This identifies open research problems such as: the definition of the design hydrograph, t...
