SPRING 2016
HOMEWORK No. 13
- A watershed in coastal Southern California
has a drainage area = 6.8 mi2, 24-hr rainfall = 4.5 in, and time of concentration = 1 hr. The current
estimated curve number CN = 80.
What reduction in CN would be necessary through watershed improvements in order to
reduce the peak discharge to less than 80% of the current
value? Use ONLINE TR55.
- What is the Darcy-Weisbach friction factor in a channel with Q = 7.2 m3/s, b = 1.2 m, z = 1,
So = 0.0006, and n = 0.013?
[Hint: Find critical slope using ONLINE CHANNEL 04].
