浮遊流砂による貯水池の堆砂に関する研究

Abstract

For the sake of the flood control and water resource development, many dams areconstructed now in our countly. But generally the rivers in our country transport a lot ofthe sedimenots into the reservoir, then many reservorirs constructed years ago have becomecompletely filled with sediment deposits.Therdore the sedimentation in reservoir is one of the most important problems in riverengineering at present.In this paper, authors studied experimentally on the sediment deposition of the suspendedsediment in a rearvoir, and made clear some intresteresting characteristics such as concentra-tion-distributions, relations between suspended and deposited sediment, and sediment bedprofiles.With the use of the experimental results, authors established an analytical equation forthe deposited sediment bed profile. Experiment shows fairly good agreements with the resultsby the above equation. But the estimation of the constant involved should be furtherdiscussed.
