Scanning Sonar for Underwater Infrastructure Inspection

Submitted by Anonymous (not verified) on Mon, 07/30/2018 - 14:12

One problem with using divers or remotely operated vehicles to perform underwater inspections of hydraulic structures is that frequently-encountered conditions of poor visibility increase the inspection time and reduce the inspection quality. Commercially available scanning sonar systems can be used to overcome this limitation because sonar works in even highly turbid water to produce detailed images of underwater infrastructure. Scanning sonar can also collect survey-grade bathymetry and three-dimensional (3D) point clouds of underwater features.
