COASTAL MORPHODYNAMICS-MANAGEMENT & MARINE GEOLOGY
The activities of the Coastal Morphodynamics-Management and Marine Geology Group focus on the study of the coastal zone, with its main aims being the education/training of undergraduate and postgraduate students and basic and applied research.
- Research themes
- Morphology and sedimentology of the coastal and marine environment.
- Study of the hydrodynamics, sediment dynamics and morphodynamics of the coastal zone on the basis of high frequency field observations and modeling.
- Modeling of coastal waves and wave-generated currents for the diagnosis/prognosis of their interactions with coastal works.
- Study of the marine geo-hazards (e.g. submarine slumps, faults and the presence of gases within the bed sediments) and their impacts on coastal and sub-marine works (ports, route surveys for power and fiber optic submarine cables and offshore pipelines, platforms and drilling sites)
- Prospecting and evaluation of marine aggregates and the environmental impacts of their mining.
- Monitoring and modeling of the drainage basin hydrology and the transport and fate of sediments and pollutants in the coastal environment.
- Study of the impacts of climate variability and change (e.g. sea level rise, storm surges and waves, river floods, droughts) and their management at the drainage basin scale.
The nature of the coastal processes requires interdisciplinary approaches and cooperation with the other academic staff of the Department of Marine Sciences as well as with scientists from academic institutions in Greece and abroad.
The Group also provides services (applied research) in relation to the above research themes to local and national authorities, international organisations and the private sector.
