Benefits of AquaCoustic Surveys.
AquaCoustic uses a range of technologies to survey dams and reservoirs, including:

• Scanning sonar
• Boat mounted profiling sonar & laser
• Survey through ice
• Video
• 3D sonar
• 3D laser
• Inspection class Remotely Operated Vehicles (ROVs).
  

DAMS & RESERVOIR SURVEYS

In addition to the usual sensors for dam inspections, AquaCoustic has designed and built portable 3D SONAR and 3D LASER systems that can be deployed in a variety of ways.

AquaCoustic can provide accurate data to help in ensuring the safety, effectiveness, and environmental sustainability of dams and reservoirs.

Inspection Class ROV

• Capture video images of scour areas, sink holes and trash racks.
• Sonar scanning in confined areas.
• 3D Sonar profiling.
• Dye testing for water currents / leaks.
• Tunnel inspection, sonar and video.
  
  
  
  
  

CAD ready data:

• Rock trap volume surveys.
• Identify and measure scour patterns and undermining from plunge pools or sink holes.
• Determine earthquake values by accurate measurement of slope profiles from a single point.
• Gather detailed data from hard-to-reach areas such as under overhangs, floating structures or vertical dam faces.
• Accurate data can be obtained up to the shoreline or beside vertical faces where boat soundings are not reliable.
  

High current conditions

• The profiling sonar system provides better than 12 mm (0.5 in measurements at close range.
• Our laser profiler provides better than 8 mm accuracy.
• Combined Sonar and Laser surveys for a complete understanding of asset conditions.
  

Angle of repose using Sonar below water, laser above

• Determine earthquake values by accurate measurement of dam slope profiles from a single point.
• AquaCoustic uses a single beam profiling sonar to profile the underwater portion of the survey area and a profiling laser above water
• Obtain data up to the shoreline or beside vertical structures where boat soundings are not reliable.

Tunnel inspections

• Pipe size verification
• Condition assessment
• Sediment or debris identification.
• Pre- and post-repair quality control.
• Repeat surveys to monitor conditions.
• Measure stop log guides, gates or other structures.
