Coefficient of Discharge for Free Flow Sluice Gates
This paper aims to investigate the effect of sill shape located under the sluice gate on the coefficient of discharge for free gate flow conditions. Both sill shape and sill height are studied. Shapes tested include both polygonal and non polygonal sills.

Discharge coefficient for trapezoidal side weir
The designed length of the rectangular side weirs sometimes becomes too long that makes it non-practical from the engineering point of view. In order to decrease the length of channel opening with the desired water height, this study focuses on applying ...

Uncertainty analysis of discharge coefficient of circular crested weirs
The circular crested weir (CCW) has been introduced as weirs having a high discharge coefficient (Cd). The ratio of flow head to the radius of the crest (H/R) is the most important parameter affecting the Cd, that the $${\text{Cd}} \approx a\left( {H/R} \
