5) water surface curves of natural watercourse
天然河道水面线
1.
The shortcomings of the traditional methods that trial-and-error method, approximate solution and iteration method were used to compute the water surface curves of natural watercourses resulting in large amount of calculations, low precise and complex resolving problems.
传统的计算天然河道水面线的方法是试算法,迭代法和图解法等,这些方法的缺点是计算量大、精度不高,无法控制全河段误差,将其看作是全河段总计算误差,即一复杂非线性优化最小问题,运用实数编码的加速遗传算法求解天然河道水面线。
