Question

Transcribed Image Text:Design ogee spillway for a concrete gravity dam and find the maximum flood discharge that could be disposed of safely to the downstream. It is having downstream face sloping at (0.85H: 1V), the height of spillway crest is kept at (0.85H: 1V), the height of spillway crest is kept at level (300 m), the average river bed level at the site is (190 m), the spillway length consist of (5) span having clear width (10 m) each with pier thickness = 3 m, kp=0.01, ka=0.1, C=2.2. If: D/S crest profile is given by: X1.85 = 25y And the U/S: y = 0.724 (x+0.27 Ha)" 1.85 HO.85 + 0.126 H-0.4315 H375 (x+0.27 Hd) 0.625 Neglect the approach velocity head.
