The head on the crest of a controlled overflow spillway is 2.1 m. Approach flow velocity is 2 m/s. Total bridge length over the spillway is 50 m There are 4 rounded nosed piers each 1 m wide. Abutments are rounded with head wall 90 to flow direction. Determine: a) The discharges over the spillway crest for the gate openings of 0.6 m, 0.8 m, 1.0 m, 1.2 m, and 1.4 m. b) The gate opening to transmit Q=170 m3
