摘要
运用圣维南方程组构建一维非恒定流模型,对宜兴市河网湖泊等水利工程进行了概化模拟,重点对圩区排涝泵站、闸门调度方式、河道流域面上的调蓄作用及净雨流入等进行了探讨。计算结果表明,模拟效果较好,可为宜兴市防洪决策提供科学依据。
River networks,Lakes and other ciril engineering projects in Yixing City are simulated by use of Saint-Venant equation, and one-dimensional unsteady, flow model is constructed. Emphasis is put on polders pumping station, gate dispatching inside, storage regulation and inflow of rainfall. The result of calculation shows that the simulation model is feasible and can provide reasonal data for Yixing＇s flood control.
