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)

Numerical modelling of contracted sharp‐crested weirs and combined weir and gate systems
Irrigation and Drainage, 2020 AbstractDischarge measurement and control structures are widely employed in hydraulic engineering applications. The objective of this study is to numerically investigate the modelling of two different structures, namely sharp‐crested weirs as Problem 1 and combined weir and gate systems as Problem 2.

Water surface profile of the trapezoidal permeable sill with sharp-crested weir on the upstream slope [PDF]
Acta Scientiarum Polonorum. Formatio Circumiectus, 2018 The aim of the study was to analyse the possibility of using dimensionless coordinates in order to determine the typical shape of the overflow stream at the gabion sill, as well as identify the flow zone therein and evaluate the characteristic dimensions

Discharge coefficient of a rectangular sharp-edged broad-crested weir
Journal of Hydrology and Hydromechanics, 2014 This paper is concerned with the determination of the relationship for the calculation of the discharge coefficient at free overflow over a rectangular sharp-edged broad-crested weir without lateral contraction. The determination was made on the basis of

Modified theoretical stage-discharge relation for circular sharp-crested weirs
Water Science and Engineering, 2012 A circular sharp-crested weir is a circular control section used for measuring flow in open channels, reservoirs, and tanks. As flow measuring devices in open channels, these weirs are placed perpendicular to the sides and bottoms of straight-approach ...
