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

Discharge coefficients for ogee spillways
Water Supply, 2022 Abstract Discharge over an ogee weir is related to the length of the weir, upstream total head above the weir crest and the discharge coefficient. The discharge coefficient is influenced by several factors; in this study, some parameters that influence discharge coefficients of ogee weirs are investigated. These factors include: the weir

Prediction of the discharge capacity of piano key weirs using artificial neural networks
Journal of HydroinformaticsThe discharge capacity of the piano key weir (PKW) is an important flow feature which ultimately decides the design of PKWs. In the present research work, the different architecture of artificial neural networks (ANNs) was employed to predict the ...

Experimental Coefficient of Discharge for Leaky Woody Dams in Clear Water Conditions
Journal of Flood Risk ManagementNatural flood management (NFM) uses natural features and processes to manage flood risk. Although natural processes in river flow are well known, their use to manage floods has been only deeply analyzed since recent years, and the hydraulic behavior and ...
