A practical guide to using side-scan sonar for coastal-structure work.
It explains what the tool can and cannot tell you, with real-world examples and field guidance.
Side-scan sonar offers fast, qualitative views of long sections of coastal structures, helping engineers plan inspections, monitor changes, and document construction. The material covers how images are created, interpreted, and used alongside other methods to verify conditions and movements around rubble mounds, walls, and armor units. It also outlines limitations, such as how wave motion can affect image quality and why the tool is not a substitute for design decisions.
- How side-scan sonar works and what a typical image reveals about coastal structures
- Ways to apply the technique for reconnaissance, maintenance, and documentation
- Limitations and best practices to improve image quality in challenging environments
- Examples from field work on jetties, breakwaters, and other coastal installations
Ideal for engineers, planners, and field teams involved in coastal protection, harbor maintenance, and related projects.
