Abstract：To understand the effect of the spatial heterogeneity of underlying surfaces and man kind activities on the soil erosion and sediment yield in small watershed, a distributed model for sediment yield in small basins based on isolated storm events is developed. The model can respectively simulate space-time processes of runoff formation and sediment yield for the small watersheds with various water-and-soil conservation measures (various using type of land), and is helpful for the optimization of these measures in the management of the small watershds. The model is finally calibrated and validated by measured data in the Heicaohe basin. Results showed that the proposed model can reasonably simulate rainfall-runoff-sediment transport in small watershed.
