Results indicate that the observed salt fluxes under the two wind conditions show a marginal difference. Under the steady wind condition, a DBL with a constant thickness of 3.5 cm is observed right above the deposited sediment. The molecular diffusion is found to be the dominant mechanism for salt transport within the DBL. The latter can suppress the hydrodynamic enhancement on the exchange of substances between deposited sediments and overlying water.
