Underwater Acoustic Imaging for Dams

360-degree acoustic imaging is a great tool to investigate the conditions of the underwater portion of a dam structure. Also known as a sector scan, these tools can create detailed images in water conditions in which there is zero visibility. By stitching several of the images together, a complete picture of the underwater portion of a dam can be created. This, in turn, can be combined with above-water digital photography to create a complete image of the entire structure.

Acoustic imaging can be completed on vertical surfaces such as pier noses, trash racks, lock walls, and more. It is also effective in gathering images of the river bottom to monitor scour conditions by changing the orientation of the survey head.  This technology can be used in conjunction with underwater dive inspections to get a highly detailed report.
