CFD-Based Modeling for Computing Discharge Coefficient of an Ogee Spillway

open access: yes, 2023
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. The discharge coefficient of an ogee spillway is greatly affected by the ratio of an operating head and design head.
