摘要
利用2003-2005年水文站水位观测资料和相应气象站点雨量观测资料,应用相关分析方法,确定旱涝多发的皖境淮河流域不同子流域内水位对流域内降雨的响应时效,结果表明不同子流域水文站的水位对有效降雨量的响应时效存在差异,主要集中在2-4天.选取3个有效降雨与水位相关程度较高的子流域,分别建立降雨-水位关系统计模型.利用2007年7月上旬淮河流域大水资料进行试验,结果表明所建模型的水位预测效果较好.
In this paper, based on the hydrological and meteorological observation data, a study of relationship with water level and precipitation in Huaihe River basin of Anhui, where flood and drought were occurred usually, was presented. Using a correlation analysis technique, relationship of water level and precipitation were found out. It is shown in the results that the relationships of different fields were various. In general, the water- level should be raised after 2- 4 days later when precipitation were occurred. Finally, the models of water-level change were built based on the statistical characters in 3 fields, which with high relativity with water-level and rainfall. And the models were applied during July early on 2007. As results of application shown that the models are capable for water level forecasting.
