Various activities, including aquaculture, submarine tailings disposal of mine waste rock, and the drilling of oil wells in coastal waters, generate fine particulate matter that is transported by ocean currents before settling to the ocean bottom.

Lorax designs and applies numerical models for simulating the production, transport, deposition, and re-suspension of sediments. These sediment transport models utilize currents taken from measurements or from a numerical hydrodynamic model to simulate the movement of suspended solids in lakes and oceans.

The settling rate of suspended solids depends on the concentration, diameter and density of individual particles. Often, small particles will congregate into flocs that have different settling properties than individual particles.

Sediment re-suspension can be an important process that depends on current speed near the bottom of a lake or ocean, and the cohesiveness, or shear strength of the sediments on the bottom.

Lorax includes all of these factors in their numerical models of sediment transport in order to produce the best results.
