抄録: | According to our field investigations and some results of wash load concentration calculatedby the method presented in our preceding study, it was made clear that the yield of wash load wasrather active in stream channels than in bare slopes in many drainage basins. Therefore, how toyield wash load in channels as well as in slopes should be made clear in order to develop a predictivemethod of wash load transport.The purpose of the present study is to reveal the yield process and its formulation of wash loadin channels. We consider both the erosion of sediments and the mixing action between theflowing water and pore water as dominant phenomena which are subject to the wash out of siltsfrom channel sediments. It is discussed from theoretical grounds and experiments how the yieldof wash load takes place through each mechanism, and then the yield processes are formulated. |
