Question

3.8.
The annual flow of the Colorado
River below Glen Canyon Dam is
approximately 107 acre-ft / yr, where
an acre-ft is the volume needed to
cover one acre, one foot deep ≈ 4.35
104 ft3. This flow is not steady
over the year but varies from season
to season. At a point where the river
is 200 ft wide and 10 ft deep (assume
for this problem that the river has a
rectangular cross section), what is the
velocity of the river, averaged over
the whole year?
