ABSTRACT: 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.
