Create a 10 mi2 watershed with Lag time of 45 minutes. Use
HEC-HMS to determine the direct runoff hydrograph due to rainfall
with the following Rainfall Excess:

Use SCS UH method and show the direct
runoff hydrograph at the basin outlet.
Note: Take a screen
shoot of the model result and report the peak discharge.
