This study has investigated theoretically longitudinal dispersion of suspended fine particles with settling velocity and revealed the dispersing behavior from the initial to the stationary stages in tidal oscillatory currents. A Stokes layer of the oscillatory current plays a remarkably significant role on dispersion of settling particles when the mixing time in cross-section is larger than the period of tidal oscillation. When the settling velocity exceeds a certain value, however, the dispersion coefficient of particles decreases with increasing settling velocity. In an oscillatory current with linear profile, settling velocity of dispersing particles decreases the value of the dispersion coefficient all over the values of the settling velocity.

More about this publication?
  • The Journal of Marine Research, one of the oldest journals in American marine science, publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. Biological studies involving coupling between ecological and physical processes are preferred over those that report systematics. The editors strive always to serve authors and readers in the academic oceanographic community by publishing papers vital to the marine research in the long and rich tradition of the Sears Foundation for Marine Research. We welcome you to the Journal of Marine Research.
