Scour depth downstream sharp-crested weir
Journal of Engineering and Applied Science, 2023 Weirs are hydraulic obstructions constructed across an open-channel flow causing a rise in water which is useful to convert water to the channels upstream as well as using these structures as a measuring device.

Influences of sedimentation on overflow properties of sharp-crested weir
International Journal of Sediment ResearchA sharp-crested weir is the simplest type of weir and is mainly used for discharge measurement in open channels. The surface profile of an ogee weir also is designed based on the lower nappe profile of the free jet passing over a sharp-crested weir.

Laboratory experiments and numerical model of local scour around submerged sharp crested weirs
Journal of King Saud University: Engineering Sciences, 2020 The use of theoretical models, with multiphase flow (air, water, and sand), is lacking in prior research for the simulation and management of erosion around hydraulic structures. In this research, flume experiments and a Computational Fluid Dynamic (CFD)

A Note on the Discharge over Full-width Rectangular Sharp-crested Weirs and Weirs of Finite Crest Length [PDF]
Journal of Applied and Computational Mechanics, 2023 The head-discharge relationship for sharp-crested weirs is developed based on the energy consideration upstream and at the crest of the weir. The discharge for weirs of finite crest length is estimated by correlating the critical depth and total energy ...
