A Study of Impacts of Global Sea Level Rise on Salt Water Intrusion Into the Changjiang Estuary

摘要

Using the methods of empirical correlation and numerical analogue computation of the longitudinal distribution of two-dimensional chlorinity and combined with the actual situation of water supply in the Changjiang Estuary, a calculation and analysis have been made in this paper of the impacts of sea level rise of 0.5—1.0 m in the Changjiang Estuary in the next century on the probabilities of hourly chlorinity of more than 100×10-6, 200×10-6 and 250×10-6 during the dry season st Wusong station and on the intrusion distance of the isohalines of 1×10-3 and 5×10-3 during the ebb tide stand of the dry season in the South Branch as well as on the longitudinal distribution of the chlorinity of the South Branch in the most unfavorable situation with the minimum monthly mean discharge during the special dry year.
