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
  • 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.
  • We provide slope measurements 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
  • Obtained 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.
