1.You need to design a concrete (n = 0.013) channel that will convey 50,000 GPM. It is to be a trapezoidal in cross section with a bottom width of 7.5 feet. The side slopes are to be 1.33:1 (H:V) and it is desired to have the depth of flow constant at 2.0 feet. How many inches should the channel drop in 350 feet of length?

a).0.5in

b).6in

c).12in

d).16in

2.A natural trapezoidal channel (n = 0.03) with a bottom width of 10 feet, side slopes, s = 2 and depth of flow of 4-feet. The bed slope, So = 0.4%. What is the discharge?

a).200cfs

b).275cfs

c).425cfs

d).575cfs

3.A rectangular concrete (n = 0.013) channel has been surveyed to drop 6.512 feet in a four mile stretch and has a bottom width of 6-feet. The depth of flow is 4 feet. What is the flow rate?

a).16cfs

b).33cfs

c).46cfs

d).69cfs
