Discharge coefficient for trapezoidal side weir

open access: yesAlexandria Engineering Journal, 2015
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

open access: yesApplied Water Science, 2021
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} \
