critical error

The traditional methods for computing critical water depth of open channel with trapezoid section ( h k) are trial and error method, graphic method, approximate solution method and iteration method, whose shortcomings are rough precision, large computation amount and complex resolving problem.

目前计算梯形断面明渠临界水深hk的常用方法有试算法、图解法、近似公式法和迭代法，它们存在计算精度不高、求解复杂等缺点。
