Abstract

Abstract

Lateral circulation,which can be generated in estuarine systems by a variety of mechanisms,plays an important role in the momentum balance and mass transport in estuaries. A three-dimensional hydrodynamic model (EFDC),combined with field measurement data in 1989 and 2002,is used to investigate the lateral circulation in the Lingding Estuary. The model have successfully reproduced the hydrodynamics and salinity distribution during the flood and dry seasons. Two cross-sectional profiles in two different regions are chosen to examine the lateral circulation and salinity dynamics in different periods. The results show that lateral circulation is poorly developed in the Lingding Estuary and features more local characteristics because of its special bathymetry and hydrodynamic conditions. The lateral circulation in the Lingding Estuary is generated by the interaction among river flow,tidal currents and bathymetry,and the mechanisms in two sections are different. In this study,we conclude that lateral circulation is not significant for the dynamics of Lingding Estuary.
