I.
Sediment transport by waves and currents in the turbulent marine bottom
boundary layer:
- numerical and analytical modelling of turbulence (One- and Two-equation
turbulence-closure numerical models), and of coherent vortex structures
(discrete-vortex, analytical and numerical models), resulting from the
interaction between waves and currents in the seabed boundary layer.
- modelling the associated detailed processes of sediment entrainment and
transport, above both plane and rippled beds, including morphological changes
(stability of the seabed).
- developing improved practical engineering formulations for sand transport in
the coastal zone based upon detailed, validated, physical process models.
II.
Surface wave propagation in water of finite depth:
- analytical wave modelling in shoaling water.
- modelling Eulerian drift above rippled and rough seabeds.
- modelling resonant surface-wave/seabed interactions and sand bar formation.
