Concepts of Flood Control

Flooding is a temporary overflow of water that submerges or covers the the usually dry land. It can also be defined as the overflow of the excess amount of water that covers a huge area of land which is normally dry.

Runoff data have been collected for a 4-hour storm over a 120 acre watershed as indicated in the table. If the total volume of water infiltrated during the storm was 3.0 Ac-ft and the Phi Index is 0.1 in/hr, sketch the rainfall hyetograph with EVERYTHING labeled appropriately. Also, report the depth and volume of precipitation (in inches and Ac-ft, respectively) for each 1-hour period.

Plot the resulting DRH due to 3 rainfall events, assuming a phi-index of 0.20 cm/hr. • Recall that the phi-index represents the rate of infiltration. • The hydrograph plots RUNOFF rates, where runoff = precipitation - losses. Note that the rainfall magnitude is reported as total rainfall depth in 6 hrs, so convert infiltration as a total for every 6 hr period. b. Assuming a baseflow of 30 m3/s, what are the ordinates of the storm hydrograph?
