1994年6月中旬,广东省西、北江发生了自1915年以来的特大洪水灾害,灾情严重,损失巨大。 6月8日,9403号强热带风暴在湛江登陆后继续往北移动并减弱成低压槽与北方冷空气相遇,使北江流域和西江上游连续降大到暴雨。北江流域降400mm以上的有2.9万km~2,占北江流域的62％;西江流域降100mm以上的有20万km~2。由于降雨强度大、范围广,造成山洪暴发,江河水位急涨,发生了1915年以来未有的特大洪水。6月19日北江石角站出现14.72m的洪峰水位,超过50年一遇水位,比100年一遇水位14.74m仅差2cm;6月20日西江高要站出现13.62m的洪峰水位,超过50年一遇的水
In mid-June 1994, an extraordinary flood disaster occurred in the west and north rivers of Guangdong Province from 1915 onwards. The disaster was serious and the loss was huge. On June 8, the severe tropical storm No. 9403 continued to move northward after it landed in Zhanjiang and weakened into a collision between the low pressure trough and the northern cold air, causing the continuous fall in the upper reaches of the North River and the Xijiang River to heavy rains. There are 29,000 km ~ 2 in the Beijiang River valley that drops over 400 mm, accounting for 62% of the Beijiang River basin. There are 200,000 km ~ 2 in the Xijiang River valley that drops 100 mm or more. Owing to the heavy rainfall intensity and wide range, the outbreak of flash flood caused the rapid rise of river water level and the unprecedented flood occurred since 1915. On June 19, there was a peak water level of 14.72m at Shijiao Station of the Beijiang River. After a water level exceeded 50 years, it was only 2cm below the water level of 14.74m in 100 years. On June 20, the peak water level of 13.62m occurred at Gaoyao Station of the Xijiang River, 50-year-old water
