Discharge Characteristics of Skew Sluice Gates
Publication: Journal of Irrigation and Drainage Engineering
Volume 126, Issue 5
Abstract
Discharge characteristics for a skew sluice gate, ranging between the two extreme cases of a side sluice gate and a normal sluice gate, have been explored. The concept of an elementary discharge coefficient was utilized for obtaining the discharge through a skew sluice gate. Based on experimental investigation, equations for elementary discharge coefficients for skew sluice gates in free- and submerged-flow conditions were obtained. These equations describe the behavior of the elementary discharge coefficients for large ranges of the upstream water depth to gate opening ratio, tailwater depth to gate opening ratio, and skew angle. Using these equations, it is possible to obtain the discharge passing through a bifold skew sluice gate and it is expected that these equations will be useful to obtain the discharge through sluice gates having any plan shape.
