Water quality model for the river network has been studied in this paper.

本文研究了河网水质数学模型。

West river North river, river network horizon, the boat ran high, lion dancers Huan.

西江北江，河网纵横，龙舟激昂，狮舞人欢。

Taihu basin belongs to plain river network and river systems are connected with each other.

太湖流域属于平原河网区，水系相五连通。

The research on regional water supply measurement technology in the plain river network was brought forward.

本文在前人研究的基础上，率先提出在平原河网地区进行区域供水计量技术研究。

Because the simulation range of river network is wide, the water quality is mostly simulated in numerical method.

由于河网的模拟范围很大，多数情况下只能采用数值方法进行水质模拟。
