A simple reservoir has a linear storage indication curve defined by Q/2 = S /At, where At = 1.0 hr. If S at 8 A.M. is zero /s-hr, use the continuity equation to route the following hydrograph through the reservoir. Time (hr) Inflow (ft³/s) 8 А. М. 9 A. M. 10 А. М. 11 A.

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. Time (h) Inflow (m³/s) 6 12 18 24 30 35 55 92 130 160 140
