抄録

This paper describes the mechanism of increase of water depth caused by accumulation of drifting woods at the strcade, as the third stage of a series of study on the check. As a result of theoretical and experimental research, it makes clear the following points; (a) the phenomena of diving woods at the initial stage of accumulation process is the direct cause of increase of water. (b) maximum values of backwater depth are 1-2.4 times as much as the velocity head at no accumulation. (c) the experimental result coincides approximately the calculated curve by the suggested model on backwater profile
