Titre : Developing of remote sensing technics for evaluating the spatial and temporal distribution of Hydrological paramaters in arid basins

Région : Aride

Code du projet : IC18970154 FP4-INCO

Durée : From 1997-11-01 to 2001-04-30

Descriptif
The project is built up to provide better insights in understanding surface hydrology in arid and semi-arid regions such as Mediterranean (Israel, Morocco, Tunisia) from various remote sensing of earth technics, with an emphasis on active microwaves one (space-borne radars).
The main parameters controlling surface water cycle in arid and semi-arid regions are relative distribution of bare rock area versus colluvial and alluvial sections, inclination of hill slopes, spatial and temporal distribution of vegetation, soil moisture and soil roughness. In arid regions, the maintenance of conventional watershed gauged network is both a difficult and expensive task. Because of characteristic high resolution combined with possible global coverage, space-borne synthetic aperture radar can provide a unique tool for monitoring hydrological parameters in large watersheds. The resulting high resolution map could improve hydrological modelling for which the bottle neck is due to the lack of spatially distributed physical parameters and frequent updating.
The general objective of this project is the evaluation of accurate quantitative spatially distributed hydrological parameters, such as soil roughness and moisture content, or vegetation density, by remote sensing (optical and active microwaves) in arid and semi-arid regions to improve prediction of run-off, infiltration and erosion by their assimilation in rainfall-runoff models.
