Acoustic Imaging and Profiling: A New Tool for Underwater Inspection

摘要

Use of underwater acoustic imaging and profiling technology enabled the owner of the 50-year-old D'Arbonne Dam in north central Louisiana to pinpoint potential problems and make timely and cost-effective repairs.rnFor each of 20 reservoirs constructed by the state of Louisiana, the state's Department of Transportation and Development is authorized to operate and maintain the dam, water control structures, gates, spillway, and related appurtenances. Structures at these reservoirs are approximately 40 to 50 years old. The department's mandate is to ensure that the man-made impoundment structures and the attendant water-control devices are functioning to design capabilities.
