2005年6月西江流域持续暴雨,强度大、历时长,造成西江中下游地区发生特大洪水,下游控制站梧州水文站洪峰量级超百年一遇,仅次于历史调查洪水1915年,列近百年来第二位。本文分析了暴雨成因、暴雨特性、洪水形成、组合情况、洪水特性及重现期,并与94·06、98·06洪水比较,为洪水管理与防汛工作提供了科学依据。
In June 2005, the torrential rain continued to occur in the Xijiang River Basin, which lasted for a long time, resulting in serious floods in the middle and lower reaches of the Xijiang River. The peak flood level of Wuzhou Hydrological Station in the downstream control station exceeded the flood peak in history by one hundred years, second only to historical floods in 1915 and nearly a hundred years To the second place. This paper analyzes the causes of rainstorm, the characteristics of rainstorm, the formation of floods, the combination, the characteristics of floods and the recovery period. Compared with floods of 94.06,08.06, it provides a scientific basis for flood management and flood control.
