The overarching themes of this symposium are related to time and space: long-term developments and effects on small, rather than large, estuaries. The subjects may tackle fundamental questions, e.g. ecosystem stability in smaller estuaries, or applied subjects related to pollution or fisheries.




The broad themes are:

1)      Long-term trends or variability? The physical and biological environment of small estuaries.

2)      Ecosystem structure, functions and stability

3)      Ecosystem services and values of small estuaries

4)      Fisheries in small estuaries


Since the last symposium on small estuaries was held in 1976, the field of geomorphology has undergone a method metamorphosis with advances in hydrodynamic modelling, remote sensing and digital terrain models. However, accurate and pertinent field data remains of utmost importance in understanding system processes in estuaries.

While we invite abstracts exploring all aspects of estuarine dynamics, the symposium's broad themes are:


1)      Morphological trends in small estuaries - how can we expect the hydrodynamics of estuaries to change in the future? What are the implications for biota?

2)      Estuarine biota as ecosystem engineers - exploring the impact biota have on geomorphic processes

3)      Saltmarsh processes and dynamics

4)      Sediment supply and estuarine hydrodynamics


Coastal waters are complex aquatic systems that link terrestrial and ocean biogeochemical cycles. They are strongly impacted by river inflows, physical exchange with the open ocean and fluxes across the atmosphere- and sediment-water interfaces.

This session will update our knowledge of recent research and what has changed in our understanding of coastal biogeochemistry over the last 40 years. We welcome abstracts dealing with all aspects of coastal biogeochemistry covered by these themes:


  1. Pelagic  and sediment biogeochemistry
  2. Modelling of biogeochemical cycles 
  3. Management use of biogeochemical data


Coastal Management

Estuaries provide a complex and ever changing landscape that creates difficulty for those required to manage them. The mixture of economic, recreational and biodiversity values attached to these systems creates further stress in deciding on an appropriate approach, exacerbated by the long-term threat of climate change. In addition, the implementation of EU directives has challenged public and private sector bodies. We invite abstracts that explore these issues. 



The broad themes are:

1)      Understanding linkages between catchment management and the health/quality of small estuaries and other coastal ecosystems

2)      Climate change: challenges and opportunities to estuarine and coastal management

3)      Tools for effective estuary management

4)      Any other topics/case studies that inform effective estuarine or coastal management
