MIKE 21/3 Sand Transport

Analyse sedimentation's impact on ports, offshore energy, dredging, and coastal engineering

MIKE 21/3 Sand Transport (ST) offers comprehensive sand transport modelling and simulation capabilities, tailored for coastal engineers and port designers. This software enables precise assessment of erosion and sedimentation impacts on infrastructure by accurately calculating sand transport from both currents and waves, employing a sophisticated wave boundary layer approach for detailed simulations.


Built to support dynamic modelling, MIKE 21/3 ST seamlessly couples with hydrodynamic and wave analysis modules. This integration allows for effective prediction of sediment dynamics around coastal structures and tidal inlets. By forecasting port sedimentation and simulating morphological changes, this tool ensures that coastal and offshore projects are backed by the most accurate and comprehensive data available, facilitating informed decision-making and robust engineering design.
