The water level along a reach of a river is rising at an average rate of about 0.6 m/hr due to a flood. At a given cross section, the flow rate is about 2200 m3 /s at a particular instant of time. Estimate the flow rate at this instant of time at a position 3 km upstream. The average top width of the river along the reach is 600 m. First, assume that the net lateral flow along the reach is negligible. Next, rework the problem for the case where the average net lateral inflow along the reach is 800 (m3/day)/m. Provide a sketch of the flow conditions?
