1) Determine the type of water surface profile for a 2.45 m rectangular channel of 0.0004 bed slope and of 0.015 manning's roughness. The discharge is 2.83 m3/s and the measured depth is a) 1.52 m, b) 0.61 m, and c) 0.3m? 2) What is the type of water surface profile for a triangular channel with a bed slope of 0.002? The channel surface is made of finished float concert with a side slope of 2.5 m, the channel discharge is 1.8 m3/s and the measured depth is 0.5 m. 3) A finished concrete (with gravel on bottom) trapezoidal channel with a 4 m bottom width, side slope of 2:1, and a bottom slope of 0.003. Determine the depth at 600 m upstream from a section that has a measured depth of 2 m? (Step-size of 0.2 m) 4) A trapezoidal channel with a bottom width of 7 m, a slope of 0.0016, Manning's roughness of 0.025, and side slope of 2:1 has a discharge of 35 m³/s. An obstruction is added in the channel causes the upstream depth to be 3 m. How far upstream does normal depth occur? (Step-size of 0.2 m)
