Abstract :
A two-dimensional model of water flow in a hillslope which has been implemented on the massively parallel processor is described. Flow in the soil both in the saturated and unsaturated zones, evaporation and overland flow are modeled, and the rainfall rates are allowed to vary spatially. Previous models of this type have always been very limited computationally. This model takes less than a minute to model all the components of the hillslope water flow for a day. The model can be used in sensitivity studies to specify which measurements should be taken and how accurate they should be to describe such flows for environmental studies
