Numerical simulation of saltwater intrusion and storm surge effects of reclamation in Pearl River Estuary, China.

Abstract This study aims to simulate and predict the influence of reclamation on saltwater intrusion and storm surge in the Pearl River Estuary, China by using the FVCOM Surface Wave Module (FVCOM-SWAVE). The study shows that the reclamation has a great influence on tidal velocity and direction, especially in some areas where narrow waterways are formed. Reclamation resulted in an increase in salinity due to impeded runoff, and reduced significant wave height in the nearby sea area. It has a positive effect on reducing storm surge disasters. However, the geographic scope of impact has been small and there is almost no change away from the reclamation area. [ABSTRACT FROM AUTHOR]
