When mining activity results in the discharge of liquids or suspended solids to lake or coastal ocean waters Lorax utilizes three-dimensional numerical hydrodynamic models to quantify the resulting environmental impact. Lorax has adapted a modified version of the Princeton Ocean Model (POM) for simulating three-dimensional current fields. One of several modifications made by Lorax allows POM to simulate the intertidal shoreline region where the sea bottom is exposed during low tides.

When required, Lorax custom designs and develops its own models, such as C3, which was used to model currents and effluent dilution for the Capital Regional District near Victoria, British Columbia.

Depending on the application, a hydrodynamic model may include some or all of the following:

  • Tides
  • Winds
  • River and stream inflows / outflows
  • Surface ice formation
  • Shoreline and bathymetry


A hydrodynamic model may calculate dissolved contaminant dilution directly or instead, provide lake or ocean currents for use by other models designed to simulate processes such as effluent dispersion, contaminant fate, suspended solids concentration, or sediment transport and deposition.


Whenever possible, current and other measurements are used to verify the correctness of the model predictions.
