Answer #1

Rating cure is discharge vs He

Q is discharge which is directly proportional to the H^1.5

using that finding values of discharge at required heights as shown in the attachement and plotting a curve of Q vs He

Thank you

An overflow ogee crest for a spillway is to discharge 20,000 cfs. The upstream face of the crest is sloped 1:1 and a bridge is to span the crest. Flow over the spillway is to be controlled by a series of Tainter gates. Bridge piers 18-in wide (pier contraction Kp = 0.05) with rounded noses are to be provided to support the gates. The bridge spans (center to center of piers) are not to exceed 30 ft. The maximum expected...
