Characteristics of overland flow in a patchily-vegetated semi-arid hillslope, as simulated via the Saint-Venant equations. (A) Illustration of the flow depth profile (dark blue line, on the left hand axis) and the friction factor (dashed black line, on the right hand axis) for a 150Â m bare zone adjacent to 30Â m of vegetation (green lines), on a 5% slope, at the end of a 30Â minute, 5Â cm/hr storm. (B) Profile of the flow velocity for the same conditions. Longitudinal distance in both plots normalized so that 0Â m occurs on the upslope edge of the vegetation.
