鄱阳湖水系“2019.06”暴雨洪水分析

Analysis of flooding process of Poyang lake basin in June 2019

为科学防御暴雨洪水灾害,减少生命财产损失,以鄱阳湖水系“2019.06”暴雨为研究对象,分析了暴雨洪水过程、暴雨洪水特性、水库调蓄过程,并提出了防汛抗洪的建议.研究表明:本次致灾的主要因素是暴雨强度大、覆盖范围广,部分中小河流洪水超历史纪录;同时水库腾库迎洪,削峰错峰,减轻了灾害损失.

In order to technically prevent storms and floods,reduce the economic loss of life and property,the study make use of rainfall data,runoff data and storage data of reservoir.The study analyzes the rainstorm-flood process,rainstorm-flood characteristics,the flood regulation of reservoir,and puts forward suggestions for the flood control.The research shows that the main factors of the disaster are the heavy intensity and wide coverage of rainfall,and some medium-sized rivers have super historical floods.At the same time,flood-discharging,flooding peak clipping and flood peak staggering to reduce disaster losses。
