BerthWatch uses repeated sonar surveys to monitor underwater berth conditions. A Canadian-addressed case study describes three dual-axis scanning sonars, an interface unit and a sound-velocity sensor at COVE, feeding MarineLabs CoastAware. Sound-speed correction and georeferenced point clouds allow comparisons across scans. The site had little traffic or sediment deposition, so observed changes were limited; the trial does not establish quantified dredging savings.
Technical detail
Core features
Repeated scans are sound-speed corrected, georeferenced and converted to point clouds
COVE setup used three dual-axis scanning sonars, one interface unit and one sound-velocity sensor
Point-cloud comparisons support examination of scour, shoaling and changes in berth conditions
