River discharge estimation from satellite

River discharge is defined as the amount of water flowing through a river over a specified period of time. Its estimate is crucial for all the operations of hydraulic structures design, the territorial planning and the flood risk assessment and management. River discharge at a specific river cross-section is not a direct measurement, but it is calculated by measuring other hydraulic quantities such as the flow velocity and the water depth, i.e. ...

Monitoraggio fluviale da rilevamento satellitare

Although representing less than 1% of the total amount of water on Earth, the freshwater is essential for terrestrial life and human needs. Despite the existing in-situ gauging networks represent a tool for quantifying the instantaneous water volume in many river channels, we have surprisingly poor knowledge of the spatial and temporal dynamics of surface river discharge. Developing new procedures for river discharge estimation based on ...

Dikes and Debris Flows Monitoring by Novel Optical Fiber Sensors

With more than 5 million people affected, more than 1000 killed, and with estimated total damages exceeding 4.5 billion Euros just in Europe and during the last decade, floods are among the most disruptive natural events threatening our Society. Due to increase in extreme weather events and rapid socio-economic developments in vulnerable locations, the risks connected to floods in general are growing rapidly, and the awareness of these risks ...

Web-based relational database on the main levee breaches of the Po River (Northern Italy)

This is the web-based relational database on the main levee breaches of the Po River (Italy), which have occurred since the year 1800. The database contains more than 200 fact sheets that show the information for each levee failure. For each fact sheet are attached documents and maps. The access is free of charge. This database may provide a valid support in the design of defense interventions directed at the prevention and mitigation of ...

Aerofototeca

The CNR IRPI archive preserves 170.000 aerial photographs useful for stereoscopic applications. Most part of those photographs were taken during a number of surveys carried out between 1954 and 2005 in tha Padan Plain, Triveneto and Liguria (Northern Italy) but some examples date from the 1920s, 1930s and 1940s. In this documentation the effects of many floods and landslides events can be observed. In particular, we would mention the aerial ...

Control and validation of hydro-meteorological data

The analysis of hydro-meteorological data is required to verify the correct sensors functioning and possible presence of non-operational periods with missing data. When non-operational periods or malfunction occur, it could be possible  to apply procedures for missing data reconstructions and wrong data ...

Levees and bridges vulnerability

Assessment of bridge piers/abutments vulnerability to scour and overtopping hazard, assessment of levee vulnerability to seepage and overtopping hazard. The analysis is based on clearly identified criteria. Specifically, overtopping (IVS) and erosion (IVE) vulnerability indices are evaluated for each selected bridge, and the overtopping (IVsorm) and seepage vulnerability indices (IVsif) are calculated for the ...

Hydrological study of the Paglia river basin

The Tiber River Basin Authority (ABT) and the Umbria Region (Service Water Resources and Hydraulic Risk), considering the verified underestimation of the flood-prone areas in the Paglia River basin provided by the Italian PAI (hydro-geological management plan) and the update of rating curves, decided to revise the hydrological study of the drainage basin in order to re-estimate the flood hazard maps for the Paglia River reach bounded upstream ...

Modelling for real-time flood forecasting

The project activities concern: development and implementation of: 1) a semi-distributed continuous hydrological model (MISDc) for real-time soil moisture estimate and river discharge prediction in the Upper-Middle Tiber River basin; 2) a flood wave routing model (STAFOM-RCM) for stage hydrograph forecasting at some selected hydrometric stations in the Tiber River basin; support for installation of soil moisture sensors in the ...

Gestione dei Sedimenti Fluviali

Il progetto GeSeFlu nasce dalla necessità della Regione Lombardia mediante il Piano Operativo Regionale (Direttiva Comunitaria 2000/60/CE) di disporre di specifici Programmi di Gestione dei sedimenti per i sottobacini redatti in attuazione della Direttiva del Comitato Istituzionale dell’Autorità di Bacino del fiume Po (deliberazione n. 9 del 5 aprile ...

RIVERbank Surveillance bAsed on Fiber optic sEnsors

In the last decades Europe and Italy suffered many damaging floods, causing thousands of deaths, the displacement of millions of people and billions of euros in insured economic losses. Veneto Region has been also strongly stricken in 2010. The European Commission has identified the need for adaptation of risk management in several documents in order to reduce the likelihood and/or the impact of floods [1]. Starting from these remarks, the main ...

FLoods and fIre Risk assessment and managEment

FLIRE is a demonstration project aiming to the development of an integrated Decision Support System (DSS) for both flash floods and forest fires risk assessment and management. The DSS tool will be designed by using state of art tools, technologies and methods and taking into account prevention, adaptation and interaction issues. The final model will be online available to key stakeholders and relevant authorities (local and national) for the ...

Geo-hydrological hazards in the Pogliaschina catchment

The occurrence of flash floods in mountainous catchments is often associated to relevant geomorphic effects, both in the channel network (channel changes and transport of large wood), and on the hillslopes (landslides and soil erosion). The concomitance of flash floods, channel changes and landslides enhances hazards and risk associated to individual ...

Sediment management in Alpine basins

The understanding of the changing equilibrium between sediment supply from upstream and sediment transport capability of a river is important for the success of integrated water resource management. In Alpine river basins, intensive sediment transport processes and sediment continuity have a notable impact on several water management issues posing multiple use conflicts related to hydropower, ecology, flood control ...

Management of sediment transport in small mountain catchments

Sediment transport in small mountain catchments (drainage area < 10-20 km2) is a fundamental process for the equilibrium and the dynamics of the whole channel network. At the same time, sediment transport can create high-risk conditions due to the occurrence of extreme phenomena such as debris flow, hyperconcentrated flow, and flood with intense bedload, usually triggered by intense and short duration rainfall. In order to properly manage ...

Decision matrices for the assessment of fluvial processes in mountain streams

Decision matrices may contribute to mountain watershed management by defining coherent event scenarios that take into account the type of flow processes (e.g., water floods with bedload, debris flows), their geomorphic effects, and the interactions with hydraulic control ...

Identification of the channel network in the Autonomous Province of Trento

The accurate representation of the channel network is fundamental in cartography. The increasing availability of high-resolution, LiDAR-derived DTMs provides an excellent topographic basis for the representation of the channel network, but requires innovative techniques for managing and processing ...

Hazards in karst areas and mitigation strategies

The high fragility of karst terrains, and the deriving vulnerability to a number of possible events, together with the presence of significant natural (first and foremost, groundwater), landscape and historical resources, are at the origin of the project activities, aimed at the safeguard of karst environments and the mitigation of the related ...

Hydrometeorological data resources and technologies for effective flash flood forecasting

Flash-floods develop at space and time scales that conventional observation systems for rainfall and river discharge are not able to monitor. Consequently, the atmospheric and hydrological generating mechanisms of flash-floods are poorly understood, leading to highly uncertain forecasts of these ...
