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.
