2. A 2.5 m wide rectangular channel conveys m wide rectangular channel conveys water at a normal depth of 2 m. In a part of the channel, the channel width is expanded to 5 m. The local energy loss due to this expansion is about 10% of the upstream velocity head. If the channel slope is 0.03% and the Manning roughness coefficient is about 0.012, calculate the water depth over this transition and show the situation with a simple sketch.
