Scale Effects on the Discharge Coefficient of Ogee Spillway with an Arc in Plan and Converging Training Walls [PDF]
Civil Engineering Infrastructures Journal, 2016 Dam spillways are the structures that lead rightly and safely the outflow downstream, so that the dam integrity can be guaranteed. Many accidents with dams have been caused by an inadequate spillway design or insufficient capacity.

Determination of Ungated Ogee Spillway Length so as to Pass Design Flood Safely
Turkish Journal of Civil EngineeringBecause the flowrate over an ungated ogee spillway depends on the net head of the water conveyed in the approach channel and because the energy losses depend on the flowrate, computation of the spillway discharge for a given gross head of water in the ...

A new approach to determine the discharge passing over ogee spillway
International Symposium "The Environmental and The Industry", 2019 The main purpose of this study is investigation of flow over an ogee spillway experimentally and comparison with the analytical results. An experimental study was conducted to obtain discharges and heads over an ogee spillway. 30 different discharge and flow depths of flow in physical model were measured.

Simulation of Ogee Spillway by FLOW3D Software (Case Study: Shahid Abbaspour Dam) [PDF]
Journal of Hydraulic Structures, 2022 Dam's weir is one of the most important dam structures that play a significant role in flood routing in the dam reservoir. Since the dam's level significantly affects the storage, changing the level and increasing its height can increase storage volume ...

A Numerical Simulations on the Flow over Ogee Spillway with Tainter Gate
Journal of Korea Water Resources Association, 2004 In this study, overflow behaviors through a partially open tainter gate mounted on a standard ogee spillway were investigated by using the FLOW-3D. The results indicated that the discharge coefficient is in the range of 0.685 to 0.723. A relation of gate-controlled discharge to free discharge was proposed and a reasonable correlation between the free ...
