Sediment Transport and Morphodynamics

Continental margins are constantly changing their morphology due to multi-scale physical and biological interactions that lead to sediment erosion and deposition. Changes in morphology in turn affect the flowing fluids (water and air) in not only physical but also biogeochemical ways.

Research at the Department of Sediment Transport and Morphodynamics aims to disentangle the evolving dynamics of morphology from event-associated change to decadal, centennial and longer time scale development – so that geologic, atmospheric, biologic and anthropogenic effects at these different time scales can be discerned separately.

We develop and apply hybrid numerical models that combine process-based solution of physical processes which can be mathematically well described and data-driven parameterization of less-understood, intrinsic self-organization behaviors and biological factors. With the numerical tools, we target questions related to

  • Sediment transport and morphodynamics in coastal areas, shelf seas and continental slopes
  • Interaction between biota and morphodynamics
  • Transport and early diagenesis of particulate organic carbon (POC)
  • Impact of biota and morphodynamics on early diagenesis of POC
