MIKE 21 ST FM and MIKE 21/3 MT FM

Sediment transport using sand (2D) and mud (2D & 3D) modelling

This one-day, hands-on course will teach you the fundamentals of sand transport modelling and mud transport modelling for both pure currents and a combined waves and current regime. You will learn how to set up a sand/mud transport model and simulate the sand/mud transport and morphological changes using a coupled setup with flow and wave models. We shall also discuss when to apply a 3D approach.

The ST module in MIKE 21 Flow Model HD FM calculates the sediment transport capacity, the initial rates of bed level changes and the morphological changes for noncohesive sediment (sand) due to currents or combined currents/waves. The MT module calculates the erosion, transport, settling and deposition of cohesive sediment. Mechanisms such as flocculation and resuspension are also accounted for.

Typical applications include the ability to predict sediment transport and resulting morphological changes together with suspended sediment concentration along coasts and in estuaries. This will support the investigation and optimisation of coastal and estuarine infrastructure projects.
