A STUDY OF IMPACTS OF GLOBAL SEA-LEVEL RISE ON SALT-WATER-INTRUSION INTO THE CHANGJIANG ESTUARY

Using the methods of empirical correlation and numerical analogue comp utation of the longitudinal distribution of two-dimensional chlorinity and combined with the actual situation of water supply in the Changji ang Estuary, a calculation and analysis have been made in this paper o f 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 X 10(-6), 200 X 10(-6) and 250 X 10(-6) during the dry seaso n at Wusong station and on the intrusion distance of the isohalines of 1 X 10(-3) and 5 X 10(-3) during the ebb tide stand of the dry season in the South Branch as well as on the longitudinal distribution of th e chlorinity of the South Branch in the most unfavorable situation wit h the minimum monthly mean discharge during the special dry year.
