【Abstract】 Based on the boundary layer theory and critical depth theory,this paper suggests the hydraulic design method for the flow measuring flume in the parabola shape canal with a long throat as well as the discharge calculation formula,with the concrete calculation examples to illustrate the design procedures.This design method can flexibly change the shape parameters of the flow measuring flume in the parabola shape canal with a long throat without the rated experiments so that the calculation is simple and highly accurate.更多还原
