Abstract
The calculation of critical depth of the open channel with a standard U-shaped cross-section is difficult because of its complicated formula. In order to solve this problem, a simplified formula of the critical depth was derived by using the optimized fitting method and taking minimal standard residual difference as an objective function. The simplified formula meets the engineering requirement, and its calculation has the advantages of simple, fast, and high accuracy.关键词
