Flushing Capacity of a Stored Volume of Water: An Experimental Study

This paper presents a systematic analysis of the hydraulic flushing capacity stored volume water to remove sediments. is based on 90 laboratory experiments in which sediment evacuated was measured for varying initial volumes water, three bed slopes, and sizes. The consisted rapid emptying reservoir by means suddenly opening tilting gate downstream. produced an accelerated flow eroded mobile reservoir. efficacy flushing, herein defined as ratio sediments released, increased with slope, decreased increased. In relation size, while results obtained coarse medium sands were very similar each other, fine sand affected existence apparent cohesion bed. comparison sands, this reduced given hence, flushing.
