实时洪水预报系统应用实例分析

Case Analysis of Real-time Flood Forecast System Application

针对山区多支流汇入河段的洪水特点,利用实时洪水预报软件系统和实时水雨情数据库技术,建立了受多支流汇入影响明显河段的洪水过程预报模型。对建模原则和方法及注意事项进行了分析论述,该模型具备人机会话和实时校正的功能,提高了多支流汇入河段的洪水预报精度,对洪水预报系统在山区河流的应用作了尝试。

Based on the flood characteristics of river sections with multiple tributaries inflow in mountainous area,the real-time flood forecast software system and real-time rainfall database technology are applied to establish a flood process forecast system on the river sections affected obviously by multiple tributaries inflow in the mountainous area.Modeling principles,modeling method and points for attention are analyzed and discussed in the study.The model has the functions of man-machine dialogue and real-time check,increasing the accuracy of flood forecast on the river sections with multiple tributaries inflow,and its trial application is conducted for the flood forecast in the rivers of mountainous areas.
