Control of Sediment Discharge from Side Weir by Slanting Strips

Abstract

In taking the discharge by the side weir in the river, the discharge is as large as possible comparing from weir width and the sediment discharge is as little as possible. The bed in front of the weir is made down by the slanting strips. And the following problems are investigated. 1) How long is the bed near the wall made down by the size of the slanting strips with relation to sediment diameter and shear stress. 2) How much is the sediment discharge decreased by the variation of the bed in front of the side weir. 3) How is discharge of the side weir varied by the slanting strips
