Guidelines for low cost subsurface sonar imaging, Ottawa River/Quyon, Québec, test case: M103-3/16-2015E-PDF

"Recently, there have been consumer grade, low cost, side scan imaging sonars capable of imaging the floor of a lake, a river or a coastline. These tools are targeted for sport fishing but are also capable of providing an image of the lake and river floor. These tools, which are easy to use, can have scientific and technological applications, such as the subsurface geomorphological mapping of lake and river floors: bedrock outline, contact between sediments and bedrock, lineaments, sand waves location and various forms of erosion / deposit. Consumer grade imaging sonars can partly fill the technology / scientific information gap, and are particularly well suited for the Canadian North and in remote areas. A case study was carried out in Quyon, in the Ottawa region, to determine the potential of these tools for the geomorphological mapping of a river floor, as it may relate to landslide characterization in the area. This document explains the main constraints for a high quality survey and recommends ways to overcome them”--Summary provided by publisher.
