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

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.

Numerical Investigation of Inverse Curvature Ogee Spillway [PDF]
Civil Engineering Journal, 2017 Design of water structures and their segments including spillways play an important role in water resources management and agricultural activities. In the the linear body part of an ogee spillway, for speeding up the flow rate, the flow should be transferred to the stilling basin by inverse curve so that the water energy can be reduced. This study aims
