摘要
通过求解泥沙扩散方程来研究泥沙沿水深的分布和含沙量分布沿程的变化规律,构造了一种新的差分格式——跳点格式.通过分析验证表明:这种格式算法简单,计算过程简便,稳定性好、精度较高.体现了它的实用性和优越性.
In this paper,through solving sediment diffusion equation to study the distribution of sediment concentration along with depth,creating a new difference format——a jumped node different format,the results show that the format has the practicability and superiority,for the method is simple and convenient with the high accuracy and good stability.
