Water is stored behind a sluice gate to a depth of 3 m as shown in Figure Pl 3. 16. The gate opening is 0.55 m and the channel is wide rectangular with a Manning n value of 0.035. Use a contraction coefficient of 0.6 for the gate.

a. If the gate is clear (i.e., unsubmerged), what is its discharge?

b. What is the minimum channel slope downstream for this case to prevail?
