| 摘 要： | 图解法和试算法是计算正常水深和临界水深通常采用的方法，但计算精度欠佳且计算步骤繁杂。文章提出了一个新的迭代方程用于上述2种水深的计算，并用代数方法严格地证明了该方程具有收敛性。

| Abstract: | Graphic method and trial-and-error method are the common methods that apply in computing the depth of water under the normal conditions and critical depth of water. However, these computing methods are inaccurate and complicated. The article proposes a new iterative equation that can he applied in these two computations, whose convergence can he proved by algebra. |
