Abstract : Rainfall is a major meteorological factor in water assessment in semi-arid basins. For mesoscale basins, the rainfall space-time variability is high and has a major influence on hydrological dynamics. A geomorphology-based rainfall-runoff approach is developed to account for rainfall space-time variability in a robust and flexible manner, according to changing available raingauging configurations. The approach is based on a two-step hydroinformatics protocol, firstly to analyse geomorphometry, and secondly to account for and benefit from available rainfall data.
