"Sediment Transport Modeling in Lake Michigan "
Thursday, Sept. 9, 1999
10-11 a.m.
Main Conference Room (105)

A quasi-3D suspended sediment transport model was linked to a 3-D
circulation model and a wind wave model. The nonlinear turbulence intensity
and bottom shear stresses were taken into account. The sediment
entrainment, suspension and deposition processes have been parameterized by
laboratory measurement and field data. The model was calibrated with the
measured sediment concentration data during a sediment resuspension episode
in 1994-1995.

In addition, the model was applied to the March 1998 Lake Michigan sediment
plume event. The model results were compared with the available satellite
imagery. The model was able to reproduce the general patterns of high
turbidity, and gave a reasonable depiction of sediment erosion/deposition
in the lake. The asymmetric sediment  deposition pattern in southern Lake
Michigan is discussed using a circular basin model.
