SIMULATION MODELLING OF THE IMPACTS OF SEA-LEVEL RISE SINCE THE LATEGLA-CIAL PERIOD ON THE CHANGJIANG(YANGTZE) RIVER, CHINA

Dramatic water stage rise and channel aggradation in the middle and lower reaches of the Changjiang (Yangtze) River have been recognized by previous studies. A further analysis of the data from geological, geomorphological, and paleohydrological surveys suggests that these changes might have resulted from sea-level rise since the Lateglacial period. So a mathematical model has been developed here, which reconstructs the processes of water-stage rise and channel aggradation of the Changjiang River as responses to sea-level rise since 12,100 a B.P.
