Dye Dispersion Studies
Numerical Modeling

Lorax employs customized numerical hydrodynamic models to calculate temporal and three-dimensional spatial fluctuations of state variables in both freshwater and marine environments.

Depending on the location and application, values for some or all of the following variables may be calculated:

  • Surface elevation
  • Current velocity
  • Temperature and salinity
  • Dissolved contaminant concentration

Model inputs also vary with the application, but generally consist of time-varying values for state variables on model boundaries together with bathymetric data. Model outputs may be visualized or animated in order to understand circulation properties, or be used in subsequent studies of sediment transport and mine tailings fate.

Some examples of hydrodynamic model applications include studies of:

  • Coastal, tidally-forced fluctuations in sea level and current velocity.
  • Dissolved and suspended contaminant fate.
  • Sediment transport
  • Subaqueous and submarine tailings disposal and fate.
  • Sea level increases resulting from episodic storm surges.
  • Tsunami generation, propagation and coastal amplification.
  • Oil spill transport and fate.
