摘要
针对淮河流域的特点,建立了以水动力学方法为主的河道一维、行洪区二维及对无实测资料地区采用水文学方法为辅的流域洪水演进数学模型。并提出了河道一维、行洪区二维耦合的求解方法。对占相当大比重的无资料地区径流流入干流作了技术处理,这对模型的成功建立起着重要作用。通过9次洪水的验算表明,模型具有较高的精度、较强的通用性、灵活性和实用性。为淮河流域的防洪规划提供了工具。模型的主要思路同样适用于其它流域。
According to the characteristics of Huai He river basin, a flood routine numerical model is established in this paper. This model is based on hydrodynamics method of combination I-D channel flow modeling with 2-D flood plain flow modeling, and hydrology method of no data areas modeling. The technology and skill of solving the combination 1-D flow with 2-D flow and treating the runoff in no data areas are developed, which are key to successful modeling. It is showed in the 9 times floods modeling calculations that the model has high accuracy, practicality, flexibility and universality. The model is a advanced tool of Huai He river basin flood control planning and can be used in other basins.
