Exclusion of Deposited Sediments in Reservoir by the Water Level Drop at the Downstream End

Abstract

The method of excluding the deposited sediment by dropping water level and increasing the tractive force in dam-reservoir was discussed. But, when this method is applying into the diffusive theory of river-bed variation, it is not clear that which boundary condition must be used for different width of excluding gate and river. This study is concentrated on finding such a suitable boundary condition. experimently and theoreticaly. The comparison between the theoretical curve and the experimental data shows fairly good agreement.
