Abstract

Abstract

There exists the asymmetry of current speed and duration between flood and ebb in the Changjiang Estuary. Applied the three-dimension numerical model in the Changjiang Estuary, the mean flood/ebb current speed and duration in the South/North Branch, South/North Channel and South/North Passage under different river discharges, tide and water depth were given out quantitatively by the numerical experiments. The dynamic causes of the asymmetry of flood/ebb current speed and duration are explained in the view of mass conservation by the water flux through the transect during flood and ebb period.
