文章对我国中小河流洪水的特点进行了分析,总结了中小河流洪水预报不同于大河流洪水预报的实施难点,阐述了能够有效解决中小河流洪水预报问题的解决方案,研究了具体的解决方案—分布式水文模型,对分布式水文模型的建立过程、构建模型的方法和分布式水文模型的具体构架以及实际参数进行了探讨,强调了分布式水文模型在我国现阶段中小河流洪水预报体系建立落实过程中的关键性及可行性。
This paper analyzes the characteristics of floods of medium and small rivers in China, summarizes the difficulties in implementing flood forecasting of medium and small rivers, which are different from the flood forecast of large rivers, and expounds the solutions that can effectively solve the flood forecast problems in small and medium rivers. The specific solutions - Distribution Hydrological model, the establishment process of distributed hydrological model, the method of constructing model and the specific framework of distributed hydrological model are discussed, and the actual parameters are emphasized. At the present stage, the distributed hydrological model emphasizes the establishment and implementation of medium and small river flood forecasting system In the key and feasibility.
