| Abstract: | Based on the calculation theory for even -flow in trapezoid open channel, the author analyzed the basic principle and procedures of iteration method to solve the normal water depth value of channel and proposed a direct calculation formula of normal water depth in trapezoid open channel for optimal hydraulic section. This iteration calculation formula possessed properties including fast convergence, high accuracy and convenience for use, and can be operated through computer program. |
