2.) Build a Snyder Unit Hydrograph for the following:

Length is 8 miles, Length to Centroid is 3.9 miles,

the timing coefficient is 1.8 and the peaking

coefficient is 0.8 and a drainage area of 20 square

miles. Assume the storm duration is the lag time

over 5.5 (tl/5.5). and the base is 4 times the lag

time. See book for reference. Must include W50,

Tp, Lag Time, W75, and draw the full graph.
