河北省运东区“2005.07”暴雨及其“四水”转化分析

Analysis of the "2005.07" Rain-storm and Its "Four-water" Conversion in the East of the South Canal of Hebei Province

2005年7月23-24日，沧州市南运河以东的沧县、黄骅等区域普降暴雨，日降雨量达293．7mm，较为罕见，流域内沥涝面积1．08万hm^2（16.2万亩）。文中通过实测资料对本次暴雨、径流进行了分析，给出了在现状条件下运东区次暴雨“四水”转化特征，对以后该流域的水资源规划、洪水资源利用等具有重要的参考价值。

From July 23th to 24th in 2005, the regions of Cangxian and Huanghua etc. in the east of the South Canal of Cangzhou fell rain-storm widespreadly.Exceptionally, the day rainfall reached to 293.7mm. The area of water logging in the river valley is 10 800 hm^2（162 000 mu）. Analyzing this rain-storm based on the data which were measured actually, we deduced the ＂Four-water＂ conversion characteristics of the rain-storm in east of the canal under the present condition,which is of referential value to the water resources programming of the river valley and the using of the flood resource.
