Short Course Description

This classroom course provides dredgers with an overview of acoustic instruments used at various stages in dredging projects.  At the end of the module, the student should gain the following knowledge. 

  • Understand basic acoustics and how temperature, salinity and pressure variations affect sonar signals.
  • Be familiar with various acoustic sensors: their design, their function, and their applications
  • Be comfortable selecting the appropriate acoustic sensor at the correct time in a dredging project’s work-flow. 

The course focuses on the following acoustic instruments and their application. 

  • High-Resolution Scanning Sonar. Application: site survey and clearance and diver supervision.
  • Dual Axis Sonar for real-time siltation monitoring. Application: dam reservoir siltation management; trigger for dredging operations.
  • Multibeam imaging sonar. Application: site supervision and slope monitoring
  • Real-time dredge monitoring for cutter suction dredges, backhoes and clamshell grab dredges
    • Single beam echosounder
    • Dual Axis Sonar
    • Multibeam echosounder
  • Multibeam Echosounders and Unmanned Surface Vessels for bathymetric survey
  • EK80: combination acoustic doppler current profiler and split beam wideband echosounder. Application:  real time turbidity and environmental monitoring.
  • Sub-bottom profilers. Application: detection of solid objects below the mudline. 

Course Format:  The short course will be conducted in classroom style over a half day (1300-1700) and will include up to 100 participants from government agencies, the private sector, non-profits, academia, and other organizations.  Instructors will include technical leaders from the public and private sectors.  Course participants will be provided with access to all class materials and presentations.
