1. Explain three main application of HECRAS in Hydraulic Engineering. (10 marks) 2. A bridge is to be built across a rectangular channel carrying flow of 200 m³/s at certain depth. The construction has caused the width of the channel to be reduced. Analysis with assumption and sketches, the depth of flow upstream, downstream and under the bridge. (10 marks) 3. A channel is required to convey 10 m³/s of water at a mean velocity of 1.25 m/s. (a) Calculate dimensions of the most effective section for trapezoidal, parabola and semi-circle shape. (8 marks) (b) evaluate which channel shape in question 3 (a) is has the least wetted perimeter? (2 marks) 1. Explain three main application of HECRAS in Hydraulic Engineering. (10 marks) 2.
