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 ...

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

Application of Surrogate Modeling in Stochastic Analysis of an Ogee Spillway Structure
International Journal of Mechanical System DynamicsABSTRACTThis study investigates the hydraulic performance of an Ogee spillway under varying flow rate conditions, gate opening heights, and spillway widths. Numerical simulations using Flow‐3D, incorporating the (k‐ε) turbulence model and Large Eddy Simulation (LES), were employed alongside surrogate models using MATLAB codes and LP‐TAU to predict flow
