Experimental Study of Variation Sediments and Effective Hydraulic Parameters on Scour Downstream of Stepped Spillway

Abstract

The most complicated problem that threatens the spillway's overall stability is local scour downstream of the spillways due to hydraulic jumps and flow disturbance. A series of experiments were conducted in the laboratory of the Water and Soil Research Center to investigate the scour downstream of the hydraulic jump formed on the stepped spillway.Experiments were conducted under different approaching flow discharges, tail-water depths and sediment sizes. The optimal design of parameters including; type, crest and slope of

Experimental Study on Scouring and Silting and Channel Planning Based on the Entrance Area of Shenqiu Wharf

“…Based on the physical model and numerical simulation, Xiaoli Yang et al studied the effect of sediment control and discharge of sediment retention weir by taking the Derisubaoleng Reservoir as an example [17]. Dah Mardeh Arman et al studied the change of erosion and deposition in the downstream of a stepped spillway through a physical model [18]. Hua Fu and Jiongxin Xu took part of the Yangtze River and part of the Yellow River as examples to analyze the influence of river erosion and deposition [19,20].…”
