钦江-茅尾海丰、枯水期盐水入侵的盐度分布特征:以2021年盐水入侵为例
Salinity distribution characteristics of Qinjiang Maowei Sea saltwater intrusion during high and low water periods:Taking the saltwater intrusion in 2021 as an example
摘要
Abstract
The Qinjiang-Maowei Sea area is significantly affected by saltwater intrusion.Based on MIKE 3,this paper constructs a three-dimensional numerical model of saltwater intrusion.After detailed verification,the process of saltwater intrusion during the wet and dry seasons is simulated to study the salinity distribution characteristics of saltwater intrusion.The results show that during the wet season,the salinity level gradient in Maowei Sea is greater,while during the dry season,the salinity level gradient in the Qinjiang River channel is greater.During the period of rising and resting,most of the Qinjiang River channel is in a completely mixed state,with adequate vertical mixing of salinity.The upward movement of saltwater during the dry season is more intense,with the longest and average distance of saltwater upstream increasing by more than 50%compared to the wet season.关键词
