Sediments and Hydrodynamics

Partrac Geomarine are experts in sediment transport & tracking, scour assessment, dredge processes, beach processes, seabed mobility assesssment and coastal process impact assessments.

Dredge Monitoring

The process of dredging requires careful management and monitoring to enable ports and marine developments to continue functioning within environmental licence conditions. .

We have developed a range of monitoring approaches to help our clients effectively monitor and manage dredging activities.

Partrac’s expertise includes:

  • 3D plume mapping, using the commercial ADCP-Sediview method.
  • Depth profiling using autonomous turbidity sensors.
  • Real-time monitoring buoys for pre-, during-, and post-dredging environmental compliance monitoring.
  • Time-integrating and time-series sediment traps for sediment quality investigations.

Sediment and Scour Monitoring

Through the processes of erosion, transport, and deposition, fluvial, estuarine and coastal sediments are in a state of dynamic equilibrium.

Activities such as jackup rig placement, cable laying, offshore wind, wave and tide farm construction and coastal protection, structures can mobilize and redistribute sediments, creating seabed scour.

We are World leaders in the field of sediment and scour monitoring and use a range of cutting edge methods to monitor sediments in aquatic environments.

Partrac’s expertise includes:

  • Alarmed, real-time turbidity monitoring
  • Spatial sediment flux assessment and modeling using Sediview and MIKE21
  • In situ particle size measurement
  • Towed, multi-instrument package systems
  • Sentinel in-line time-integrating suspended sediment traps
  • Submersible water samplers for sensor calibration and sediment quality
  • In situ direct measurement of surface sediment stability (using Partrac GeoMarine’s ‘Voyager’ benthic flume series, and Cohesive Strength Meter)
  • Point sediment flux assessment using integrated ADCP-OBS systems
  • In situ real-time scour depth measurement (long-term, unattended)
  • Point bed-level change measurement (to millimeter resolution)
