Structural and construction considerations
Apply contraction coefficients (( K_p = 0.02 ), ( K_a = 0.20 )) to calculate effective length: [ L_e = 90 - 2 \cdot (5 \cdot 0.02 + 0.20) \cdot H_e ]

In design, the discharge coefficient ( C ) is not a fixed number. It depends on the ratio of the actual head ( H_e ) to the design head ( H_d ), the slope of the upstream face, and the spillway's height relative to the riverbed. Determining the true design head ( H_d ) often requires an iterative process to balance the required discharge with the effective crest length.
