太湖流域河网水流运动模拟研究

How to Simulate Flow Motion in River Network of the Taihu Lake Basin

本文在以往研究的基础上,利用距离提取陆域宽度,采用最短路径法,考虑河道过水面积、流量模数等因素,对陆域面上的调蓄作用进行相似模拟。为减少计算工作量,避免受计算机容量、计算工作量及资料的限制,对天然河网湖泊进行合并及概化,考虑区域工程情况及其运行方式以及破圩后的水流情况,建立了河网水流运动模型,在太湖流域防洪调度中得到了应用。

This paper made a similar simulation of the water storage adjusting on land territory, by using distance to extract the width of land territory, applying the shortest path method, and taking the cross-section area and flow modulus considered. In order to decrease computational effort and avoid restriction of computer capacity and other factors, natural river network and lakes should be generalized and merged. A model of river network flow motion was established according the concerned factors such as water structure operation. The model has been used for flood control and dispatch in the Taihu Lake Basin.
