Book Description
"The study is to determine the feasibility of further commercial navigation improvements to the connecting channels, locks, and harbors on the upper four Great Lakes, and the extent of any federal interest. Preliminary feasibility studies have been completed. In response to the commercial navigation proglems, needs, and opportunities, several alternative structural plans were evaluated... A non-structural plan... and a No action plan were also evaluated."--Syllabus.

Book Description
In conjunction with the Great Lakes connecting channels and harbors study, this report examines the potential damage to the shore and shore structures due to an increase in vessel size. The areas considered in this report are the United States shorelines along the St. Marys, St. Clair and Detroit rivers. The potential for shoreline or shore structure damage due to an increase in vessel size was reviewed on both a conceptual and site-specific basis. Ship-induced waves were ruled out as a damage mechanism since the analysis showed that the contemplated increases in vessel size would not significantly affect wave heights in the nearshore zone. Propeller wash was discounted for similar reasons. Ship-induced drawdown was determined to be the major potential damage mechanism. While larger ships potentially produce more damage, this potential is significant only in severely restricted channel sections for the size increase considered here. By far the most significant factor in ship-related damage potential is vessel speed. In almost all areas, the effect of an increase in vessel size could be eliminated by a reduction in vessel speed of 1-2 mph. (Author).

Development of a Predictive Model to Assess the Effects of Extended Season Navigation on Great Lakes Connecting Waters. Appendix B. Observed Vessel Induced Water Level Drawdowns

Pages : 522
Book Description
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 User's 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. Mary's River caused by passage of commercial vessels. All monitored passages during this contract period (10/84 to 10/85) 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. (FR).
