The formula Q = 3.32LH^3/2 is used to find the maximum water discharge over a spillway before the water overflows the main part of the dam. Q is the discharge in cubic feet per second, L is the length of the spillway, and H is the depth of the spillway below the level of the dam. Find H when Q is 3000 cu. ft. per second and L = 60 ft.© BrainMass Inc. brainmass.com November 24, 2022, 12:02 pm ad1c9bdddf
This shows how to calculate the depth of a spillway in a given situation.
