Designing Ogee-crested spillways to maximize discharge efficiency while minimizing cavitation risk.
A trapezoidal dam (concrete, ( \rho_c = 2400 , \textkg/m^3 )) has height 40 m, crest width 5 m, base width 30 m, water depth 40 m. Ignoring uplift, find FS against overturning about toe. (Hint: Divide trapezoid into rectangle + triangle, compute weights and moments) Answer: FS ≈ 2.1 (depends on exact geometry). fluid mechanics dams problems and solutions pdf
