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

Objective

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.
Expected Outcome

The expected output are the followings :
* generalisation of SPOT/Landsat-TM methods of classification for image segmentation function of roughness and vegetation density,
* evaluation of SAR data to derive indices of soil roughness and moisture,
* development of ad hoc hydrological models able to make use of remote sensing data.
The project represents an effort to bridge the significance of soil properties derived from high resolution remote sensing with existing hydrological modelisations. Derivation of hydrological surface indices from remote sensing and their implementation in spatialised rainfall-runoff models will be first developed on relatively small units very well instrumented, test watersheds in Neguev Desert. The extension will be applied in larger scale over two real size basins in Morocco and Tunisia.
The validation of the significance of these indices will be performed at two levels :
* at the level of the extraction of hydrological parameters from satellites data, by comparison within specific sites in the basins with ground and surface remote measurements,
* at the level of predictions of the runoff models, by hydrometric measurements of out flows at the outlet of the entire basins and some subunits.
