为提高洪水的预报精度和预见期,充分利用现有防洪工程进行优化调度,减少滞洪区的使用,把洪水造成的损失降低到最小程度,淮河干流洪水预报决策支持系统应运而生。该系统软件编程宗旨是:以水文数据库为基础,从实用的角度出发,建立预报计算库、实用方法库、图形显示库、专家知识库、研究成果库、水文数据库,构成相对独立又相互关联的模块,以 In order to improve the prediction accuracy and forecasting period of flood, it is necessary to make full use of existing flood control projects to optimize the operation, reduce the use of flood detention areas and minimize the losses caused by floods. The flood forecasting decision support system of the mainstream of Huaihe River came into being. The purpose of the software programming of this system is to base on the hydrological database and to set up the forecast calculation base, the practical method base, the graphic display base, the expert base, the research base and the hydrological base from the practical point of view, and constitutes relatively independent and interrelated Module to
