Water flows underneath a sluice gate to a mild reach in an open channel. At the end of chis reach a weir is built to develop the required navigation depth upstream. After the weir, the channel has a steep slope. Sketch the water surface profile along the channel.

A wide rectangular channel consists of two reaches. The first reach has a slope of 0.005 ft/ft while the second one has a slope of 0.0002 ft/ft. The discharge per unit width is 25
 /s. Determine whether a hydraulic jump will be formed or not and if so, where. Sketch the water surface profile in the channel. The Manning coefficient n = 0.015.
