    Abstract

    A transient one-dimensional finite-difference model describing the partitioning of precipitation between surface run-off, soil moisture storage and deep percolation, through the coupling of saturated and unsaturated zones, has been implemented in a geographical information system including data on vegetation cover derived from the Landsat Thematic Mapper. The model was used to simulate both the rainfall excess and the resultant outflow hydrographs for a small arid zone drainage basin in the Andean regions of Argentina. The overall hydrograph shape, peak discharge, run-off volume and flow duration are predicted within a relative squared error of 13.2%.
