Application of Surrogate Modeling in Stochastic Analysis of an Ogee Spillway Structure
International Journal of Mechanical System Dynamics, Volume 5, Issue 2, Page 290-311, June 2025.ABSTRACT This 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 ...

Unsteady flow past a sharp crested weir
, 2017 The present study focuses on the numerical simulation of flow past a rectangular sharp crested weir. A commercial software Star-CCM+ is used for the purpose. The governing equations are the Reynolds Averaged Navier-Stokes equations.

A Study of pressure fluctuation caused by hydraulic jump in stilling basin [PDF]
مهندسی منابع آب, 2018 A stilling basin is one of the energy dissipaters downstream of a spillway. The place of maximum pressure caused by jet impact and the effect of various factors on the amount and location of pressure are important factors in designing of stilling basin ...

Experimental investigation on sharp crested rectangular weirs
, 2020 Sharp crested rectangular weirs used for discharge measurement purposes in open channel hydraulics are investigated experimentally. A series of experiments were conducted by measuring discharge and head over the weir for different weir heights for full width weir. It is seen that after a certain weir height, head and discharge relation does not change.

Discharge Coefficient of Broad Crested Weir [PDF]
, 1962 Several mathematical Studies have been attempted to calculate a discharge coefficient of a broad crested weir by some reseachers. Those investigations follow from the assumption that a curvature of a stream line in the spilling flow varies linearly ...
