Marine Outfall Studies:

Description   Field Measurements
Projects    

Description

Marine outfall studies are carried out to assess the assimilative capacities of receiving waters and to provide the optimum location and length of the outfall pipe.  Typically, a programme of field measurements is undertaken to provide data for engineering purposes and to assist in the calibration and verification of hydrodynamic/dispersion modelling.




Field Measurements

The field measurements generally consist of a combination of the following:-

  • Current Profiling
  • Recording Current Measurements
  • Drogue or Float Tracking
  • Dye Dispersion Tests
  • Tide Level Measurements
  • Meteorological Measurements
  • Bathymetry (Multibeam or Single Beam)
  • Topography (in intertidal zone to above the HW mark)

When a potential route/location has been identified further field data may be required, such as:-

  • Sidescan Sonar
  • Magnetometer
  • Sub-bottom Profiling
