What is the flow calculation for arch dam flooding?

(1) Intersection method of wave flow and weir flow;

(2) Saint Venants formula: Om 8 BH2=27 Vg (3) Shockleys formula: Om=0.9 [H/(H-0.827)] BH3/2

(4) American Watercourse Test Station formula: gm 27V8 (B/b) 02b1 ÷ 28=For local material dams, gradually breaking sails. Laugh: Yellow Silver Containing Committees formula: Om=0.29

6. There are many calculation formulas for g B 4. bmH5bmbm=KoABAH2, and the corresponding calculation method should be determined according to the calculation conditions.
