WebbA sluice gate, which controls flow rate in a channel by simply raising or lowering a vertical plate, is commonly used in irrigation systems. A force is exerted on the gate due to the difference between the water heights y/ and y2 and the flow velocities I'/ and 1'2 upstream and downstream from the gate, respectively.
