Hydraulics of an Ogee Spillway with a Curved Plan: The Cade of Germichai Dam [PDF]
مهندسی منابع آب, 2016 The Crest of an Ogee spillway with a curved plan is longer than that of one with a straight crest; therefore, its capacity for the overflow at any reservoir level is higher than that of the straight-crested spillway. Thus it is a preferred design in most

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.

CFD-Based Modeling for Computing Discharge Coefficient of an Ogee Spillway [PDF]
, 2022 The basic functionality of the spillway is to control the flow and safely convey the excess flow while keeping the structure stable. An ogee spillway is commonly used due to its high discharging capacity.

Computational modeling of flow over an ogee spillway
Computers & Structures, 2015 This paper presents an investigation into the hydraulics of regular ogee-profile spillways. The free-surfaces of the fluid for several flow heads as measured in the hydraulics laboratory are used as benchmarks.

Application of ANSYS-Fluent Software for Innovative Stepped Dissipation Blocks Arrangement in Ogee Spillway [PDF]
E3S Web of Conferences, 2023 The Ogee Spillway is one of the most crucial flood control structures, and it is developed at the same time as dams. The Ogee Spillway's downstream portions experience scouring due to flow, a problem that persists in reality.

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 ...

Experimental and Numerical Modeling of the Gated and Ungated Ogee Spillway
, 2023 Spillways are hydraulic structures that allow dams to release and convey surplus water or flood from the reservoir to the downstream channel. The spillway is a safety structure that prevents the overtopping of the dam. Many dam failure disasters were due
