An inflow hydrograph is given for a reservoir that has a weir-spillway outflow structure. The flow through the spillway is governed by the equation Q = 3.75Ly3/2 (cfs), where L is the length of the weir and y is the height of the water above the spillway crest. The storage in the reservoir is governed by S = 300y (ac-ft). Using ∆t = 12 hr, L = 15 ft, and S0 = Q0 = 0, route the inflow hydrograph through the reservoir using the storage indication method.
