Abstract

An improved 3-D ECOM-si model was used to study the impact of seasonal tide variation on saltwater intrusion into the Changjiang River estuary

especially at the bifurcation of the North Branch (NB) and the South Branch (SB). The study assumes that the river discharge and wind are constant. The model successfully reproduced the saltwater intrusion. During spring tide

there is water and salt spillover (WSO and SSO) from the NB into the SB

and tidally averaged (net) water and salt fluxes are 985 m3/s and 24.8 ton/s

respectively. During neap tide

the WSO disappears and its net water flux is 122 m3/s. Meanwhile

the SSO continues

with net salt flux of 1.01 ton/s

much smaller than during spring tide. Because the tidal range during spring tide is smaller in June than in March

overall saltwater intrusion is weaker in June than in March during that tidal period. However

the WSO and SSO still exist in June. Net water and salt fluxes in that month are 622 m3/s and 15.35 ton/s

respectively

decreasing by 363 m3/s and 9.45 ton/s over those in March. Because tidal range during neap tide is greater in June than in March

saltwater intrusion in June is stronger than in March during that tidal period. The WSO and SSO appear in June

with net water and salt fluxes of 280 m3/s and 8.55 ton/s

respectively

increasing by 402 m3/s and 7.54 ton/s over those in March. Saltwater intrusion in the estuary is controlled by the river discharge

semi-diurnal flood-ebb tide

semi-monthly spring or neap tide

and seasonal tide variation.
