        By using non-destructive inspection equipment, ultrasonic and schmidt hammer, this research performed non-destructive inspection of underwater concrete for more efficient management in underwater concrete structures. And based on instrumented rebound hardness and ultrasonic pulse velocity, we developed the underwater concrete structures-strength estimation models using artificial neural network.

        In this study, one of nondestructive evaluation (NDE) techniques for the effective maintenance of underwater concrete structures are investigated: Ultrasonic Pulse Velocity Method and Rebound hardness Test. Currently, lots of ROV(Romotely Operated Vehicle) Systems to inspection Underwater Concrete Structures are being considered.
