Purpose and Scope: This manual presents structural and operational solutions to ice problems on rivers that are used for navigation throughout the winter. These solutions will contribute to efficient, cost-effective, reliable, and safe navigation during ice periods. This manual also presents guidance for developing River Ice Management Plans for specific rivers or river systems. The information used in preparation of this manual largely derives from experience and knowledge gained during the five-year River Ice Management (RIM) Program (1984-88) conducted by the U.S. Army Corps of Engineers.
