Why MIKE 21/3 Mud Transport?

Model the transport of mud and the interaction between mud and the bed

Analyse erosion, transport, settling and deposition of cohesive sediment in marine, brackish and freshwater areas using this state-of-the-art mud transport model that takes 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.

All of the physical processes modelled by MIKE 21/3 Mud Transport’s multi bed layer approach

Simulate all stages of the dredging process

Study the spreading and behavior of sediment spill determined by geotechnics, sediment properties, dredging methodology, hydrodynamics and sediment transport with the built-in dredging module. Use this information to analyse increased suspended sediment concentrations, morphological changes and to optimise the design of silt curtains to mitigate dispersion of turbidity plumes.

Model suspended transport of fine grained non-cohesive sediment

Even though MIKE 21/3 Mud Transport (MT) is designed to calculate cohesive sediment, you can activate sand transport formulations when required. Take advantage of this capability in cases where a certain percentage of the bed material is in the fine sand fraction that may be transported both in suspension and as bed load.

Estimate siltation rates to support port channel design and optimisation

MIKE 21/3 MT offers powerful insight for port professionals. You can accurately estimate siltation rates to design a new approach channel or to deepen existing channels. Use the information from your models to optimise navigation, maneuverability and reduce the need for maintenance dredging.

Model bed load and mixed sediment transport

Rely on our groundbreaking Near-bed transport model for bed load and mixed mud and sand transport modelling. To represent mixed sediment transport more accurately, calculate the transport of sand for combined waves and currents near the bed and consider simultaneously suspended load for pure currents in the remainder of the water column. Plus, you can account for sand spilling into the water column from dredging operations.

Assess the impact of a tailing dam break, fulfil legal requirements and address potential scrutiny

Better assess the impact of a tailing dam break

To represent the potential impact of a tailing dam break, users can simulate non-Newtonian fluids with MIKE 21/3. The “Mud, Debris or Oil” feature of the HD module allows users to define constant fluid properties (fluid density, Bingham fluid viscosity and yield stress). The Mud Transport module can simulate more complex cases by varying fluid properties in time and space, to model, for example, the mixing of non-Newtonian fluid with water.

Additional capabilities & unique features

In suspension, fine grained sediment may shadow areas over a time span, which can be critical for the survival of light-depending benthic flora and fauna. It may also deposit in areas where deposition is unwanted, for instance harbour inlets. Furthermore, pollutants are prone to adhere to cohesive sediment. If deposited in ecologically sensitive areas, it may affect the local flora and fauna and water quality in general. MIKE 21/3 MT can be used to analyse the effect of sedimentation on vegetation, biology and sediment inhomogenity to mitigate these concerns.

Apply MIKE 21 Spectral Waves (SW) 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 MT, 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 MT 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.

MIKE 21/3 MT 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.
