摘要
本文针对太湖流域研制了全流域水文数学模型,该模型包括河流、湖泊模拟、边界条件模拟、降雨径流模拟、工程情况及控制运行方式模拟以及骨干河网中水流运动模拟五个方面。模型经1984、1985两年资料进行了上述五个方面的全面率定和检验,模拟结果与实测基本吻合。本模型全面通用,因此可以用来研究太湖流域洪水、枯水及调度等诸方面课题,本文简要地介绍应用该模型研究围垦的影响、规划工程的防洪效果及设计典型年选择三方面问题。
This hydrological system model for Taihu Lake Drainage Basin consists of five submodels, namely: model for network channels and lakes, model for boundary conditions; model for rainfall and runoff; model for hydraulic projects and their management; model for unsteady flow in network channels. The model was calibrated and tested comprehensively using the observed data in 1984 and 1985. The results are consistent with those observed. The model has been applied for studying flood, drought and management of Taihu Lake Drainage Basin. As an example of applying, the influence of land reclamation from lake on flood damage, the flood damage reduction after all projects completed and the choice of design flood year were introduced briefly in this paper.
