Sediment Resuspension and Transport: Notes from the Tripod Program

Barry M. Lesht, Environmental Research Division, Argonne National Laboratory

Objectives:

  1. Determine threshold criteria for initiation of resuspension of the bottom sediments in the Lake Michigan coastal region associated with episodic events,
  2. Estimate the magnitude and direction of the horizontal near-bottom sediment flux during episodic transport events.
