Abstract: The improved COHERENS model is used to understand the dispersal and mixing processes, stratification, and circulation within the plume of the Changjiang River estuary during the spring tide under 6 ms-1 of south-southeasterly steady winds in the flood season. Modeled results show: (i) a part of the surface Changjiang River plume expands eastwardly and southeastwardly in the form of cloudy patchiness; (ii) there is an increase in the thickness of the upper buoyant plume within the Changjiang River estuary; (iii) the stratification is enhanced by wind within the plume of the Changjiang River estuary; (iv) modeled stratification parameter (φ) ranges from 50 to 450 Jm-3; and (v) longitudinal landward and seaward circulations.
