Watershed Properties and Flow

The last of the watershed properties were found.  The average slope was found to be 5.26% and the longest hydraulic length was found to be 30,750 feet.  These two were found using four topographic maps.  Using the SCS time of lag, the time of lag was calculated to be 2.422 hours.  With all of the watershed properties the peak flow was found using HEC-HMS.  The flow was found to be 3,157 cfs.  This was done using a c value of 150.
