摘要
在前人研究的基础上，提出了梯形明渠临界水深近似计算公式，并据此建立了迭代初值关系式。用本文方法求解临界水深，不仅精度高，适用范围广，而且很简便。
n the basis of past studies, the authors have proposed an approximate formula for calculating the critical water depth of trapezoidal channel. Using this formula. an expression for initialvalue iteration was established. This method has the advantages of high precision, applicable to alarge range, and simplicity'
