流域洪水模拟通用模型结构研究

Study on the structure of the universal model for river basin flood simulation

在分析流域水流特性的基础上,提出了流域可分解为一系列特征对象和流域洪水运动由水位场确定的概念.特征对象由基本元素组成,将节点水位作为模型基本变量,通过各种流域基本元素间的水量交换函数,采用数据驱动运行机制建立了流域洪水模拟通用模型,并用实例验证了方法的可行性.

Based on an analysis of the river basin flood characteristics, it is proposed that a river basin can be divided into a series of objectives with different characteristics. The objectives consist of basic elements, and the flood evolution in the river basin depends on the water stage field. Then, with the nodal water stage taken as the basic variable, a universal model for river basin flood simulation is established by use of the inter-element water volume exchange function and the data driving mechanism. The feasibility of the model is verified by some examples.
