Abstract

The paper focusses on connectivity in the context of infiltration-excess overland flow and its integrated response as slope-base overland flow hydrographs. Overland flow is simulated on a sloping surface with some minor topographic expression and spatially differing infiltration rates. The goal of the model is to relate the cell-scale processes to the behaviour of the hillslope as a whole, examining the response to a range of simple storms on randomly generated surfaces of different roughness, some with no structure and others with a structure developed by erosional processes acting on an initially random surface. The model has also been applied to a 10-year rainfall record, using both hourly and daily time steps, and the implications explored for coarser scale models. Initial trails incorporating erosion continuously update topography and suggest that successive storms produce an initial increase in erosion as rilling develops, while runoff totals are only slightly modified. Other factors not yet considered include the dynamics of soil crusting and vegetation growth
