Alter the rainfall in Example 5-1 by using the following hourly cumulative measurements:

Assume that there is a detention pond at point B of the basin that is used for flood control. Assume a storage-discharge relationship S = k × Q, where k is equivalent to 0.75 ac-ft/cfs. Prepare a graph of the outflow from the basin, with and without detention, and compare results.
