Description :
This study analyses effects of surface roughness on overland-flow by means of a model simulating depression filling, flow pathways and runoff generation. It examines the relevant characteristics of surface roughness using numerically generated surfaces. Three surface descriptions are considered. First, the sensitivity of overland-flow triggering to surface correlation properties is addressed. Secondly, effects of the short-range correlation are studied. Thirdly, combined effects of random roughness and general slope are analysed and discussed.
