With strong tide,rapid flow and turbulent tidal bore,Qiantang Estuary is a typical well-mixedone. Its saltwater intrusion is far stronger than other tidal estuaries. Based on a finite volume method withGodunov scheme,a 2D saltwater intrusion mathematical model affected by tidal bore was established. Com-bining with the field data analysis for tide,tidal bore and chlorinity,the effect of the tidal bore on saltwa-ter intrusion of Qiantang Estuary was studied. The tidal bore increases the aggravation of saltwa...
