2.31. A 5-hr storm over a 15-ac

basin produces a 5-in. rainfall: 1.2

in./hr for the first hour, 2.1 in./hr

for the second hour, 0.9 in./hr for

the third hour, and 0.4 in./hr for

the last 2 hr. Determine the infiltra-

tion that would result from the

Horton model with

k = 1.1/hr, fe= 0.2 in./hr,

and fo 0.9 in./hr. Plot the

overland flow for this condition in

=

in./hr vs. t.
