2.7. A watershed has the following characteristics:
A=2500ac,
L=3.9mi,
S=52f(t)/(m)i.
y=1%.
The channel is lined with concrete. The watershed is a residential area with
(1)/(4)-
ac lots. The soil is categorized as soil group B. Assume that the average watershed slope is the same as the channel slope. Determine the UH for this area for a storm duration of 1 hr using the SCS triangular UH method.
