Webb11 mars 2024 · In this paper, an experimental study was carried out for testing the water flow during the opening process of a bottom shaft driving flap gate. Three different opening velocities (once in 20 years, once in 50 years, once in 100 years) were selected for obtaining detailed characteristics. WebbKeywords: Vortex, Sluice gate, Hydraulic, Discharge coefficient, Vortices decay 1. Introduction Sluice gates are widely used for controlling discharge and flow depth in many irrigational structural systems. Due to the practical importance of the sluice gate as a control and metering device, the prediction of the flow

Webbof 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. 1. Introduction . Water resources management is closely related to the depletion of water resources. Webb22 feb. 2024 · Sedimentation affects the safety of dams and reduces energy production, storage, discharge capacity and flood attenuation capabilities. It increases loads on the dam and gates, damages mechanical equipment and creates a wide range of environmental impacts.

WebbThe present research describes a laboratory study of hydraulic jump in the abrupt asymmetric expansion stilling basin as an energy dissipator by changing the geometry of walls and bed roughness elements. The experiments were carried out in a horizontal flume with 10 m length, 0.5 m width, and 0.5 m depth for a range of the upstream Froude … Webb30 aug. 2024 · 1) Intake sluice gate. Built on the banks of rivers, reservoirs, or lakes, and at the head of irrigation diversion channels, to ensure and control the flow into the canal. Since the inlet gate is located at the head of the canal, it is also called the headgate. 2) Divide sluice gate.
