Numerical Study on the Flow Pattern and Hydraulic Characteristics of Flow over Converging Spillway with Flip Bucket (Case Study: Gavshan Dam Spillway (
Spillways are one of the Most Important Hydraulic Structures of Dams that Transmitted Flood Entering the Reservoir with Sufficient Safety when Capacity Reservoir Completed.To Reduce the Cost of long Spillways and Topographic Factors, Walls, Especially in the Chutes Constructed.In this study, Flow over the Gavshan Dam Spillway Comprising Approach Ch
