The physical model was constructed at 1 :60 scale and covered lower 

 Lake Huron from approximately 700 m (2,300 ft) north and northeast of the boat 

 basin to approximately 460 m (1 .500 ft) southwest of the boat basin in the 

 St. Clair River. Two types of model investigations were conducted on 10 boat 

 basin configurations — (a) a sedimentation study using a coal tracer to track the 

 sediment movement pathways and deposition areas with respect to the boat basin, 

 and (b) wave measurements inside the basin to document the optimum 

 configuration for reducing reflective wave energy.
