ダムの背砂に関する研究(I) ―貯水池における砂堆の運動機構について―

Abstract

The bed profile by the deposited sediment in reservoir for bed load generaly takesthe form of delta and the movement of this delta is very important factor on the sedi-ment problem in reservoir.In this paper, authors considered theoretically and experimentally on the hydraulicbehaviors of the delta and made clear the hydraulic properties of the front of the deltasuch as the depth and the locus of the front.With the use of the results, authors established the method to calculate the bedprofile by the deposited sediment, and verified it by the experiments
