【Abstract】 In the design of the launder, the longitudinal slope of the launder base, the net width of the launder body and the net depth of the flow within the launder are the three factors for the hydraulic calculations. Taking the rectangular launder as the example, this paper makes the derivation of the equations of each factor under the optimum hydraulic section of the watercourse, and taking the dichotomy as the example, introduces the calculating procedures of the optimum hydraulic factors under the optimum hydraulic section.更多还原
