A triangular threshold is used to control the water depth which tends to be constant upstream of an open channel. Water flows on a V-notch weir with = 90^o and the magnitude of gravity is 9.81 m/s^2. What is the water discharge upstream of the threshold when conditions are normal with a water level of 0.24 m and during a flood with a water level of 1 m?
The storage in the reach of a stream has been studied. The values of x and K in Muskingum equation have been identified as 0.28 and 1.6 days. If the inflow hydrograph to the reach is as given below, compute the outflow hydrograph. Assume the outflow from the reach at 1 = 0 as 3.5 m³/s.
