Abstract
This paper discusses the role of soils, especially their hydraulic properties, and topography, in the generation of runoff on small agricultural catchments in the eastern wheatbelt of south-west Western Australia. The heterogeneity of runoff response is studied using a spatially distributed model. Two runoff generation mechanisms, namely, infiltration excess and saturation excess, were considered in the model. The roles of duplex soils and subsurface pans are handled using a parameter (f) which describes, in a simple way, the decrease of the soil hydraulic parameters with depth from the surface.
