Integrated approach for the development across Europe of user oriented climate indicators for GFCS high-priority sectors: agriculture, disaster risk reduction, energy, health, water and tourism

project-indecis-evidenza Climate change strongly impacts the whole European territory. Drought severely affects agriculture; precipitation extremes are associated with flooding, severe damage to properties and lives; temperature extremes can increase mortality; the seasonality and availability of snow affects water resources and winter tourism; wind speed or sunshine hours affect the production of renewable energy. These relations can be studied through the computation ...

Droughts, desertification and climate change in Calabria, Southern Italy

Focus-Drought-evidenza Using long-term rainfall records obtained by the rain gauge network of the former Italian Hydrographic Service, in cooperation with colleagues in other CNR Institutes (ISAC and ISAFOM), we have studied the changes in the rainfall regimes in Calabria, Southern Italy.Applying appropriate statistical methods, we checked the completeness of the historical records, verifying consistency and missing values in the records. We used the obtained ...

Detecting rainfall from the bottom up

sm2rain-evidenza-1 SM2RAIN is an innovative system for the estimation of the rainfall, based on measurements of the soil water content. SM2RAIN considers the soil as a natural rain gauge, and by measuring temporal variations of the soil water content, it estimates the rainfall falling on the soil, adopting a “bottom up” approach. Technically, SM2RAIN relies on the inversion of the soil water balance equation that computes the repartition of rainfall in ...

Documentation and analysis of flash floods

focus-Documentazione_analisi_piene_improvvise_01-evidenza-2 Flash floods occur in small to medium size river basins, and are characterised by fast temporal evolution. Because of their intensity and short warning times, flash floods often cause not only major economic damage, but also loss of lives.An integrated approach to documentation and analysis of flash floods has to include the following issues:post-flood observations aimed at estimating peak discharge and reconstructing temporal ...

Accuracy of hydrological data for extreme events analysis and upgrade of Umbria Regional Hydrological Service’s platform

evidenza-aidesir- The improved understanding of the underlying physical processes of extreme events is closely linked to the development and verification of procedures to better control, analysis and validation of hydrological data for the description and visualization of meteorological events creating an operational "database of event" which enables to better identify under what conditions hazards ...

How much Mar Piccolo peculiarities are due to groundwater outflow

5 concettualizzazione-evidenza- The Mar Piccolo basin is an internal sea basin located along the Ionian coast (Southern Italy), and it is surrounded primarily by fractured carbonate karstic environment.In primarily karstic environments, infiltration is greater than runoff; in the karstic coastal Apulian aquifers, the groundwater discharge to the sea is more than two-fold greater than the surface discharge, notwithstanding the high discharges by wells. In such ...

Debris-flow monitoring in the Alps

monitoraggio_debris_flow-evidenza Not all that flows in creeks is water. Debris flows i.e., surges in which solid particles move together with little water, may occur in steep mountain streams, mainly as a consequence of intense rainfall. Debris flows have a high kinetic energy, and may cause major damage if they encroach buildings, roads and bridges. They are also a primary cause of landslide casualties. The video below shows an example of debris flows.The low ...

Missiaga catchment – hydrometeorological data (1983-2000)

prodotti-servizi-Missiaga_data_1-evidenza The dataset includes precipitation, temperature and discharge data recorded in the Missiaga catchment (Dolomites). The Missiaga catchment was monitored by CNR IRPI from 1983 to ...

Dikes and Debris Flows Monitoring by Novel Optical Fiber Sensors

project-DOMINIO-fronte-evidenza 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)

dbrotte_evidenza 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 ...
