Problem: A rainfall lasting lhr produced a runoff hydrograph from a
10mi^(2)
drainage basin as shown in the line labeled "Measured
Q^(inthefollowing)
table of computations. The discharge in cubic feet per sccond was measured at the beginning of each of twelve 4 hr time periods. At the beginning of the storm the base flow for the basin was 20 cfs . Determine the unit hydrograph of the basin for the storms. \table[[Period,1,2,3,4,5,6,7,8,9,10,11,12],[Houns,
