Calculation of Contraction Coefficient under Sluice Gates and Application to Discharge Measurement [PDF]

open access: yes, 2009
The contraction coefficient under sluice gates on flat beds is studied for both free flow and submerged conditions based on the principle of momentum conservation, relying on an analytical determination of the pressure force exerted on the upstream face ...

Boosting ensembles for estimation of discharge coefficient and through flow discharge in broad-crested gabion weirs

open access: yesApplied Water Science, 2022
Gabion weirs are environment-friendly structures widely used for irrigation and drainage network purposes. These structures' hydraulic performance is fundamentally different from solid weirs' due to their porosity and the existence of a through-flow ...
