Abstract:

The object of this study was to develop a method for forecasting the physical effects of the passage of commercial vessels through Great Lakes connecting waters during that period of time when traffic is normally at a minimum due to a more or less continuous ice cover. The physical impacts examined were sediment translocation, water quality effects, direct damage to existing structures, and changes in the gross hydraulic regime. Also associated with Appendix B but bound separately are Development of a Predictive Model to Assess the Effects of Extended Season Navigation on Great Lakes Connecting Waters, Final Report the Users Manual for Prediction of Vessel Impacts in a Confined Waterway Appendix A, Site and Soil Conditions and Appendix C, Observed Ice Thicknesses and Water Turbidities. This appendix contains the field measurements of short-term water surface changes at several sites along the St. Marys River caused by passage of commercial vessels. All monitored passages during this contract period 1084 to 1085 are included. Additional measurement from the authors files and previous reports are also included. The appendix is organized by site name and by date of observation. The locations and characteristics of the various sites can be found in Appendix A, Site and Soil Conditions.
