The aging of key elements of our civil infrastructure, including dams, is presenting new challenges for the development of methodology that will adequately predict remaining safe life, and identify those structures where remedial action is required. To meet this need, a new approach for non-destructive testing of large concrete dams has been developed. It combines aspects of ultrasonic non-destructive testing and seismic surveying in a new methodology Acoustic Travel Tim Tomography (ATTT).
