| Abstract: | The original flow rate formula of parobolic throat flume used for U shaped channel is implicit function and is not convenient for calculation in irrigation districts.An simplified formula is developed in this paper,with a difference between results calculated with the original formula and the new formula being less than 0.5%. |
