Description :
For this study, the water balance of the fan was computed at the rainfall-event scale through the 1992-2002 decade, thus providing consistent values of annual surface water loss by infiltration. From this set of data, a hydrological functioning of the deep unsaturated zone under sandy slopes is proposed.
