Mangrove Systems and Environments

Geomorphological landforms and processes underpin the valuable ecological functions and ecosystem services performed by river-dominated, tide-dominated and interior mangrove forest systems. At the local scale, mangrove system morphodynamics are characterized by complex interactions between tidal channel flows and shallow-flooded vegetated surfaces, with wave energy dissipation across mangrove margins. Surface elevation change in mangroves reflects the balance between surface sedimentation processes and sub-surface processes and, exceptionally, responses to hurricane and tsunami impacts. Geomorphology has a role to play in assessments of mangrove status under anthropogenic pressures and in providing insights into trajectories for effective mangrove rehabilitation and restoration.
