Questions:
- Mason, a civil engineer, needed
to determine the maximum discharge for a particular dam. He knew that the
length of the spillway was 50 feet and that its depth was 5 feet. Based on
this information, what is the maximum discharge before the water breaches
its abutments?
Answer
- Mason then decided to do the calculations
on another dam, where L = 40 feet and H = 6 feet. Compare this
dam to the one in the above problem. Which has a larger maximum discharge
and by how much?
Answer
- In designing a new dam, the decision
is that the maximum discharge should be 3000 ft3./sec. and the
length of the spillway will be 60 feet. What does the depth of the spillway
need to be?
Answer
- A second dam is being designed
where the maximum discharge will be 3500 ft3./sec. and the length
of the spillway will be 50 feet. Which dam, this one or the one in problem
#3 above, will have the greatest depth of spillway?
