A sluice gate is used to control and measure the discharge in an open channel, when the upstream and downstream water depths are 1.0 m and 0.2 m respectively. Calculate the discharge in the channel

A periodic and spectacular water release, in China’s Henanprovince, flows through a giant sluice gate. Assume thatthe gate is 23 m wide, and its opening is 8 m high. Thewater depth far upstream is 32 m. Assuming free discharge,estimate the volume flow rate through the gate.

Q1) The following data were collected during a discharge measurement operation. Compute river discharge. Width of each sub- section is (1.5)m Depth (m) V(0.2d) m/sec V(0.8d) m/sec 1.3 0.6 0.4 2.5 0.9 0.6 1.7 0.7 0.5 1.0 0.6 0.4 0.4 0.4 0.3
