| Abstract: | The formulas of the discharge and velocity coefficients of the straight wall through measuring weir of the U-shaped channel are deduced by using theoretical analysis method and the behaviour of these coefficients is discussed in this paper. The linear relations between the up water head and water depth, the critical water depth of the throat of the channel are suggested based on a lot of systematical research. |
