Abstract: Over the past 100 years the U.S. Army Corps of Engineers has designed and constructed numerous civil works structures such as locks and dams on the navigable inland waterways and coastal systems and dams for power generation. Recently, however, the potential for such undertakings has become limited, and the need for maintenance of the present facilities has become more significant. The Corps has responded by initiating and developing a Repair, Evaluation, Maintenance, and Rehabilitation (REMR) program. A research effort concentrating on the inspection and rating of tainter dam and lock gates has been developed by the project team at Iowa State University (ISU). As part of the REMR program, the research has established a consistent means of identifying potential problems for tainter dam and lock gates through the use of an inspection procedure. With this tool the engineers have the capability to analyze and evaluate the inspection information before problems become severe. Being able to rely on the functionality and structural integrity of tainter dam and lock gates as operating components of a navigation lock and dam, or a power dam facility, or a reservoir is essential. If a tainter lock gate does not work properly, navigation along the entire river may be held up, incurring large user costs. Tainter dam gates are critical for maintaining the upper pool and for use in flood control at lock and power dam facilities. If a dam gate fails, causing the loss of pool, navigation along an entire stretch of river may be at a standstill until the pool is restored. A power dam project faces decreased power generation capacity if head is lost.
