Abstract In this communication, we
aim to show our contribution towards the building of a grid containing the
water holding capacity (WHC) parameter of the soils. This parameter is used as
input data in a hydrological balance type model running at the scale of half a
square degree for estimating the soil water reservoir. The Digital Soil Map of
the World drawn and edited by FAO is the soil map we used to determine the WHC
parameter.
