  • Comparison of water supply dams’ spillway performance in Malaysia

    This paper compares the risk of dam overtopping of two rolled compacted concrete (RCC) dams in Malaysia. Uniform methodology was carried out by selecting an appropriate probable maximum precipitation (PMP) series, performing a catchment PMP/PMF (probable maximum flood) rainfall runoff routing and finally, routing the inflow hydrographs through the reservoir water body. The critical PMP/PMF ...

  • Experimental study on improvement effect of guide wall to water flow in bend of spillway chute

    In order to improve water flow in a bend of a spillway chute using a guide wall, modeling experiments with or without a guide wall under conditions of three different bend axial radii, three chute bottom slopes and three flow rates were carried out in this study. Two indexes were calculated, which are the improved water surface uniformity and the reduced rate of water surface difference in ...
