为建设彰武南海水库洪水预报调度系统,改善防讯软环境,根据水库及其流域自身的特点,在方案分析与程序编制时,重点对汇流预报计算模型和梯级水库多方式联合调度运用进行了研究开发,并在微机上实现,取得了较好效果。1 汇流计算模型的分析应用1.1 模型分析选用彰武南海水库所处流域年降雨多集中在汛期,雨量资料较早,而洪水资料有记载的只有1956、1963、1982、1996年四年资料,进行多强度的单位线参数分析比较困难。为提高预报精度,
In order to build a flood forecasting and scheduling system for Nanhai reservoir in Zhangwu and to improve the soft environment for preventing and controlling infrastructures, according to the characteristics of reservoirs and their basins, in the analysis and programming of programs, the paper focuses on the joint forecasting model and multi-mode combined operation of cascade reservoirs Development, and achieved in the computer, and achieved good results. Analysis and application of confluence calculation model 1.1 Model analysis The selection of Zhangwu Nanhai reservoir where annual rainfall is more concentrated in the flood season, rainfall data earlier, while the flood data recorded only in 1956,1963,1982,1996 four years of information Multi-intensity unit line parameter analysis is more difficult. In order to improve forecast accuracy,
