摘要：
Sluice gates are commonly used in canals for control and measurement of the flow. The discharge under sluice gates can be determined through different discharge methods. The present study proposed a new equation to accurately predict the discharge through floating type sluice gate by reading the depth of water at upstream of the gate and it reveals relationship between the gate opening and water depth. It also derived a theoretical equation for variations of sluice gate discharge coefficient under free flow condition. Effects of factors on discharge coefficient were investigated. This new model can be used to predict the performance of sluice gates with different sizes under free -flow situations.
