Abstract: Risk assessment studies considering the failure of embankment dams often require the prediction of basic geometric and temporal parameters of a breach, or the estimation of peak breach outflows. Many of the relations most ...

Abstract: The energy-momentum

Abstract: A theoretically based computational model is presented for predicting the hydraulic performance of Coanda-effect screens. These screens use a tilted-wire, wedge-wire screen panel to remove thin layers of high-velocity flow ...

Abstract: Hydraulic jacking is a serious threat to concrete spillway chutes, demonstrated by the catastrophic spillway chute failure at California’s Oroville Dam in 2017. To improve the understanding of uplift pressure and joint ...

Abstract: Offsets into the flow at joints or cracks can cause hydraulic jacking of spillway chute linings or remove rock blocks from unlined chutes. Previous articles established experimentally validated relations for uplift pressure ...

Abstract: Spillway chutes containing offsets into the flow at joints or cracks are susceptible to hydraulic jacking from injected high pressures and erosion of foundation materials caused by flow through the openings. Consequently, ...

Abstract: In recent years, design floods have increased beyond spillway capacity at numerous large dams. When additional spillway capacity is difficult or expensive to develop, designers may consider allowing the overtopping of a ...

Abstract: Coanda-effect screens exclude coarse and fine debris from a variety of water intakes. Water overflows an inclined wedge-wire screen with tilted wires that shear high velocity flow from the bottom of the water column. The ...
