The Effects of Ice on Coal Movement via the Inland Waterways.
The Inland Waterways now carry about 11% of the coal production of the United States. Significant increases in the production, use, and transportation of coal have been projected. The ability of the Inland Waterways to increase its coal handling capacity, especially during the winter has been questi...
