SaTellite based Runoff Evaluation And Mapping

project-STREAM-evidenza Water is at the centre of economic and social development; it is vital to maintain health, grow food, manage the environment, and create jobs. As well over half of the world’s potable water supply is extracted from rivers, either directly or from reservoirs, understanding the variability of the stored water on and below landmasses, i.e., total runoff, is of primary importance. In situ observations or land surface/hydrological models are ...

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 ...

Monitoraggio fluviale da rilevamento satellitare

project-RIDESAT-evidenza 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 ...

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 ...

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

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.
