| Abstract: | During the design of channel transect,the paper brings forward golden section method,that is 0 618 method. In order to reduce the calculation volume of the natural depth of water(h 0)and bottom-breadth(b)which apply trial calculation method and graphic method,and improve the calculate precision,mathematical model is built up,the writer combines example to explain the train of thought,the result shows the calculation precision is high,the correctness is tested and verified by the result which is calculated by hand.it can be referred to the hydroelectric works.$$$$ |
