The effect of the entrance geometry of a culvert on the discharge coefficient is studied. The experimental results of a sharp edge model, which is compared with Bodhaine,s, are taken as the comparison base. The curved up edge model and the curved...

whenever the surface slope of bottom intake decreases, the inflow discharge increases and or coarse grains are used in the intake. The empirical equation for estimating the discharge coefficient (Cd ) of bottom intake shows that the Cd of porous media...

key weir, the discharge coefficient in the general equation of weir needs to be known. This paper presents the results of laboratory model testing of a piano key weir located on the straight open channel flume in the hydraulic laboratory of Bu-Ali Sina...

This article adopts four high-accuracy machine learning-based approaches for the prediction of discharge coefficient of a Piano Key Weir (PK-weir) under subcritical condition located on the straight open-channel flume. These approaches consist...

Labyrinth side weirs are used as regulator outlets in river diversion structures , water
conveyance systems and sewer networks . Herein , the flow around triangular labyrinth side weir
