Abstract

Abstract

Based on the 3D numerical model with high resolution grid, the response time of saltwater intrusion in the Changjiang Estuary to the change of river discharge at Datong in different tidal pattern is studied. The calculated domain of the model includes the lower reaches of the Changjiang River from Datong to the Changjiang Estuary and its adjacent sea. The results show that the time response of saltwater intrusion to the increasing river discharge at Datong in different tidal pattern is 4.0 to 6.2 days, and is obvious longer in neap tide than the one in other tidal pattern. The response time of saltwater intrusion to the river discharge change in dry season was solved in this paper, which can be as a scientific reference when the river discharge should be used in the studies of hydrology, sediment and environment in the Changjiang Estuary.
