A wide channel having a bed slope of 0.045 and the Manning roughness coefficient of 0.025 carries a discharge of 2.0
 /s. A dam is built across the channel at which the depth of water is 1.6 m. Draw the water surface profile and estimate the distance between the dam and the high stage depth of the formed hydraulic jump.
