Abstract : U.S. Army Corps of Engineers projects across the nation have problems with ice every winter. These problems are more serious in the northern states and require considerable effort to maintain or restore normal operations. A survey of Corps projects was conducted by Haynes, Haehnel, and Zabilansky (1993) to identify these problems and their severity. This report presents a large variety of solutions to the problems identified in the survey. These solutions and techniques come from many sources, including the ingenuity of Corps field personnel and research efforts at the U.S. Army Cold Regions Research and Engineering Laboratory (CRREL). According to the survey, the most common method of dealing with ice problems is chipping the ice off. This is labor intensive, time consuming, and hazardous. It is the aim of this work to make available to the Corps much more efficient methods for controlling and removing ice. The more severe the ice problem, the more economically feasible it is to use an ice control technique. The survey identified many solutions, which are summarized under the four categories of operational, mechanical, heat, and manual. This report focuses on new solutions that have been developed to solve ice problems in critical areas. Some of these solutions involve the use of air bubbler systems, and some involve the application of heat in critical locations. These applications are usually designed to prevent ice buildup that can cause problems to normal, safe operations. In some applications, the heaters can be used to shed ice so that normal operations can resume.
