G8 Coastal morphodynamics

Objective



The overall objective of this project, being the follow-up of one under MAST-I, is to develop agreed, validated and balanced numerical modelling concepts for morphological problems in coastal areas. These will then be implemented, applied and tested by some of the leading European advisory institutes in this field, in collaboration with specialized university groups.

This objective is to be achieved by bringing basic process knowledge and modelling techniques to an appropriate level and integrating them into research models for the description of waves, current, sediment transport (cohesive, non-cohesive), and morphodynamic changes. To that end, the project is divided into six sub-projects, which are interlinked via seven working groups.

Whilst one of the sub-projects concerns the management and coordination of the project, four of them concern the constituent physical processes, namely waves, currents, non-cohesive and cohesive sediment transport, and the dynamic interactions between them and the bed topography induced by them. They cover research topics such as:

- non-linear wave propagation and breaking, non-linear wave kinematics, non-linear random waves, low-frequency waves, simple updating of computed wave fields after small topographic changes;

- wave-current-turbulence interaction in the vertical and on the bed, nearshore current modelling (1D, 2D, 3D), shoreface current modelling;

- sediment transport on rippled beds, in suspension and in the sheetflow- mode, bed roughness prediction, effects of a sloping bed;

- characterization of cohesive sediments, processes in the water column (e.g. flocculation), processes on the bed (erosion, deposition), processes in the bed (consolidation, liquefaction by waves), current-turbulence-sediment interactions, fluid mud modelling, mud morphodynamics.

The methodology involves theoretical work, laboratory experiments, field work and numerical modelling at various levels of aggregation.

The sixth sub-project has the task to integrate existing and newly generated knowledge on the constituent processes into validated numerical morphodynamic model concepts at various space and time scales, ranging from medium-term models based on detailed models of the processes to highly aggregated long-term models.

The working groups address specific tasks which go beyond the scope of a single project, such as:

- coastal profile modelling (waves, currents, non-cohesive sediment transport, morphodynamics in a cross-shore slice),

- coastal area modelling (the same in 3D),

- selection and management of datasets for model validation,

- wave-current-sediment interaction,

- wave-current-bedform interaction,

- mud morphodynamic modelling at various length and time scales,

- production of a reference book.
