Sediment dynamics of a high gradient stream in the Oi river basin of Japan

Abstract

This paper discusses the effects of the valley width for discontinuities of sediment transport in natural stream channels. The results may be summarized as follows: 1)ln torrential rivers. deposition or erosion depend mostly on the sediment supply. not on the magnitude of the flow discharge. 2)Wide valley floors of streams are depositional spaces where the excess sediment from the upper stream area is temporarily deposited. In the erosional process that follows, the sediment runs off down stream in a way that can be explained by an exponential process.
