Abstract

Abstract

The objective of this study was to investigate summertime water movement and its response to wind and tidal forces between the Changjiang Estuary and the Subei coastal area based on a high-resolution, three-dimensional numerical model. The volumetric flux and the freshwater transport from the Changjiang River and the Subei local rivers were quantified across a number of cross-shelf sections. The results indicated that, under the studied climatologic conditions, the net transport in the Subei Coastal Water is generally northward. The velocity of this northward transport reaches 10 cm/s in the shallow area. Offshore transport occurs in the vicinity of the Sheyang Estuary, with a net transport velocity of circa 7 cm/s along the 40 m isobaths. The sectional water flux is related to the tidal range, which reaches a low point in neap tide and a high point in spring tide, respectively. The tide has great impact on water movement in this area. Without the tide, the net water transport is entirely northward north of the Changjiang River Estuary and the southeastward transport along the 40 m isobaths vanishes. On the other hand, the monsoon has no significant influence on the water movement; it only adjusts the water transport in a few local areas.
