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?
