Abstract
Ogee dam spillway is one of the cheapest, yet the most effective spillway design used in dams worldwide. It has an "S"shape profile with a varying gradient, along with its profile. With sedimentary materials used to construct ogee spillway, it is prone to soil erosion, and the 'S' shape also causes rapid energy dissipation. Various studies were done to investigate the spillway shape such as adding L-section sluice on its stilling basin, numerical studies on the spillway's flow structure, surface roughness, stabilize a hydraulic jump rate and discharge capacity based on its curvature. These review paper compile a building a scale model of the ogee spillway in the study, numerical method i.e. finite method (FEM), computational fluid dynamics (CFD) and artificial neural network (ANN). The results show that while the physical experimental study is still the standard numerical methods have improved tremendously in its accuracy, therefore discovering possibilities study to improve ogee dam spillways in a more widely and comprehensive. ? 2024 Author(s).
