Inference of Grain Size Distribution for Coarse Fraction of Soils which Flow into Reservoir

Abstract

In order to examine a river bed evolution by supplying the soils which flow into a reservoir to the down-stream river, it is necessary to grasp the grain size distribution for a coarse fraction of the soils. We investigated the grain size distribution of the soils deposited on some check dams. Consequently, we found a way to infer the grain size distribution using the geographical characteristic of a dam basin.
