Mine operations can result in the discharge of water soluble effluent to lakes, coastal ocean waters, or shallow freshwater ponds where it is transported and dispersed by currents. To better assess the resulting environmental impacts Lorax uses a variety of numerical models to simulate the fate of effluents in freshwater and marine environments, including:
  • Three-dimensional hydrodynamic modeling of wind- and tide-driven currents to be used in an effluent dispersion model.
  • Transport and dispersion modeling for determining effluent dilution.

Lorax utilizes both the Princeton Ocean Model (POM) and a proprietary model, C3, to generate three-dimensional current fields for oceans and lakes that can be used for a variety of applications including sediment transport and dispersion.

The Effluent Dispersion Model simulates effluent transport by using hundreds of thousands of independent particles to represent effluent mass. These particles are moved in three-dimensions by currents provided from a hydrodynamic model or from current measurements.
