Scour Survey

Utilizing Scanning Sonar for Scour Survey

Once an image is obtained by the PC-based high resolution sector scanning sonar, several built-in measuring tools allow the operator to measure length, width, height, and area of any portion of the image desired. Quantities for backfill and rip-rap for scour holes detected by the sonar can easily be calculated utilizing these measuring tools.
