Spillway blockage caused by large wood in reservoirs
E3S Web of Conferences, 2018 Large wood (LW) elements are often transported by rivers into reservoirs during heavy rainfall events. Large wood has important environmental attributes that benefit the diversification of riverine ecosystems.

A new approach to determine the discharge passing over ogee spillway
International Symposium "The Environmental and The Industry", 2019 The main purpose of this study is investigation of flow over an ogee spillway experimentally and comparison with the analytical results. An experimental study was conducted to obtain discharges and heads over an ogee spillway. 30 different discharge and flow depths of flow in physical model were measured.

Flow simulation in a flip bucket spillway: Dakpokei reservoir case study
Tạp chí Khoa học và Công nghệSimulating the hydraulic behavior of an ogee spillway with a free jet energy dissipation form is a complex task due to the involvement of two phases: liquid (water) and gas (air).

Physical and Numerical Comparison of Flow over Ogee Spillway in the Presence of Tailwater
Journal of Hydraulic Engineering, 2006 Data obtained from two physical models were compared to the results obtained from numerical model investigations of two ogee-crested spillways. In 2001, Savage and Johnson investigated ogee-crested spillways without the effect of tailwater; the present study includes the influence of tailwater on the spillway.

Prediction of cavitation damage using SVM model based on air–water two-phase flow over dam spillway
Applied Water ScienceCavitation is one of the primary causes of breakdown and failure on chute spillways, causing surface damage and structural destruction. In this research, a three-dimensional two-phase flow over an ogee spillway was modeled using the FLOW-3D model for the
