Abstract

Resistance problem of the overland flow on complex microrelief is intricated. The difficulty in evaluating the resistance mainly comes from the variety of flow status and the complex composition of the resistance. Finding out the correlation between resistance components and influence factors is believed valuable to this problem. Because experimental data in which the resistance components could be distinguished is dramatically short, the numerical Monte-Carlo method is employed. After several representative complex microrelief, surfaces are generated randomly with Monte-Carlo method. Series of detailed numerical simulations is carried out to discuss the resistance composition of the overland flow. Numerical experiments with different flow discharges and slopes are carried out on the generated surfaces. The resistance constitution regularity shown in these simulation results is discussed. Statistics of correlation between resistance component and its influence factors are obtained.
