Determine the minimum critical elevation of the top of the reservoir, which has a spillway with a maximum discharge capacity of 5127 m³/s. The spillway has five openings, each 12.2 m wide. The crest level of the spillway is 1250 m. Assume a discharge coefficient of 0.6 for the broad crested weir. [4]
