The ordinates of a 6-h unit hydrograph are as given below:
0
6 12 18 24 30 36 42 48 54 60 66
Time (h)
ordinate of
6-h UH (m/s) 0 20 60 150 120 90 66 50 32 20 10
0
If two storms, each of 1-cm rainfall excess and 6-h duration occur in succession, calcu-
late the resulting hydrograph of flow. Assume base flow to be uniform at
10 m/s.
