There are three sediment processes models within the MIKE 3 software package:

• the Sand Transport Module (ST),
• the Mud Transport Module (MT), and
• the Particle Tracking Module (PT)

The ST module is the sediment transport module for the assessment of the sediment transport rates and initial rates of bed level change for non-cohesive sediment resulting from currents or combined wave-current flows. The MIKE 3 ST module is based on the MIKE 21 ST approach and dynamically coupled to the hydrodynamic flow model.

The MT module is used to describe the erosion, transport and deposition of cohesive and cohesive/granular sediment mixtures under the action of currents and waves. The MT module also include a dredging module which allows a dynamical simulation of all stages of the dredging process.

The PT module describes the transport and fate of dissolved and suspended substances discharged or spilled anywhere within the water column.
