Abstract
The sediment transport process on the steep slope caused by rainfall and its runoff process can be divided into two: I. process casused by rainfall impact and II. process by overland flow. However, it was very rare to deal with two processes simultaneously, and some equilibrium sediment disdcharge equations were proposed by emphasizing either of two processes. In this study, we have proposed a unified model which includes the effects of rainfall impact and overinad flow, and examined the validity of the model by the experiment. Especially, we clarified the contribution of the rainfall impact to the non-equilibrium process of sediment transport.
