Coefficient of Discharge for Free Flow Sluice Gates
Journal of King Saud University: Engineering Sciences, 1999 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 Cylindrical Weirs
Tikrit Journal of Engineering Sciences, 2006 The hydraulic characteristics of cylindrical weirs under free flow conditions were studied experimentally in order to investigate the discharge coefficient (Cd) and the influence of some significant factors and performance of weirs for discharge measuring. The experimental tests were carried out on three models of weirs in which the diameter of weir (D)

Uncertainty analysis of discharge coefficient of circular crested weirs
Applied 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} \
