Analyse erosion, transport, settling and deposition of cohesive sediment in marine, brackish and freshwater areas taking fine-grained cohesive material into account. Perform the most comprehensive simulations that consider forcing by waves, salt-flocculation, the settling process, layered description of the bed, consolidation and morphological update of the bed.

The latest update introduces enhanced hotstart functionality, utilising layer and fraction distribution as initial conditions. Users now have additional options for erosion calculations, including a new RMS shear stress formulation and the ability to specify critical shear stress for each individual fraction. Dredging simulations benefit from new spilling types, expanding the scope of modelling possibilities. Furthermore, users can access new and improved outputs, such as extended output of mean velocity, bed distribution items, and three-dimensional bed parameters. To ensure optimal performance and accuracy, the update also includes substantial refactoring and modernization.
Save time and improve your modelling workflows using MIKE Zero’s upgraded editors and viewers. Take advantage of new keyboard shortcuts and themes, improved tabbing, tear off and cascade functionality plus easier access to User Guides and Scientific Documentation.
MIKE Zero, DHI’s fully Windows integrated graphical user interface, is now better than ever and comes standard with all MIKE 21/3 software. Enjoy easy access to new MIKE Cloud applications and Cloud-enhanced functionality, plus an extended set of MIKE tools within theme-based (rather than product-based) interactive workflows. Ensure important model components such as sources and structures stay at the forefront with a new interactive, customisable floating mapping window. Lastly, the updated tabbing functionality will help you work in a more organised and efficient manner.
Apply MIKE 21 Spectral Waves to calculate the influence of waves on erosion deposition patterns.
Point sources of dissolved and/or suspended components are important in many applications such as the release of sediments from rivers, intakes and outlets from cooling water or desalination plants. With MIKE 21/3 Mud Transport, you can specify source concentrations individually as either specified concentration or excess concentration.
If the morphological changes within the area of interest are expected to be comparable to the water depth in certain areas, this software can take the morphological impact on the hydrodynamics into consideration. Typical areas where this is necessary are shallow areas where long term effects are being considered or dredging/dumping sites in shallow areas.
If several bed layers are used, a transition rate can be applied. This will cause sediment from the top layers to be transferred to the subsequently lower layers.
MIKE 21/3 Mud Transport takes advantage of the efficient parallelisation techniques implemented in MIKE 21 for the use of multiple cores and GPUs. Special techniques have also been developed to enhance calculation speed within the morphological modelling.
The Mud Transport module is based on a multi-bed layered approach where each layer is described by a critical shear stress for erosion, erosion coefficient, power of erosion, density of dry sediment and erosion function. The bed layers can be soft and partly consolidated or dense and consolidated. Consolidation is included as a transition rate of sediment between the layers and liquefaction by waves is included as a weakening of the bed due to breakdown of the bed structure.
