| 摘 要： | 本文导出了一个联系河段水质与其相邻河段水质之间的表达式,从而方便地把一个偏微分方程离散为一个代数方程。文中模拟了某叉口潮汐河道水质COD的时空变化规律,计算值与实测值吻合较好。

| Abstract: | Based on the principle of mass balance, a water quality expression of one water segment connecting with anothers is developed in this paper, It provides a real and effective numerical method to solve each section quality of a fork in a river network. By using the control valume method, it is easy to transform partial defferential equation into algebraic equation. The water quality COD changing with space and time in a river network is modeled. The computational results are good in agreement with the observed data. From the result, it is concluded that this method is suitable. |
