Contributions are solicited addressing the interaction between and interdependence of ecology and groundwater. Contributions should relate to the importance of groundwater and(or) groundwater/surface water and hyporheic zone interaction to the ecological systems and ecological processes of concern.

The following sessions are planned:

  • Session A: Interactions between surface water, hyporheic zone, saturated and unsaturated groundwater
  • Session B: Connections between ecology and groundwater recharge and evapotranspiration
  • Session C: Plant-groundwater interactions
  • Session D: Links between hydrology and biogeochemistry in groundwater
  • Session E: Modelling surface-water-groundwater systems
  • Session F: Modelling interactions between hydrology and ecology
  • Session G: Management, legal and regulatory issues
  • Session H: Bio-indicators of groundwater and surface water quality
  • Session I: Land use implications (including restoration and ecohydrology)

  • Session K: Global change (human activity, natural changes): from noises to trends
    This session includes attention to, among others:
    - long term series;
    - pertinent scales of appraisal of changes;
    - indicators of changes;
    - the importance of combining ecology and hydrology to define new sensitive tools to measure changes;
    - revisiting the current monitoring strategies/policies;
    - modelling;
    - dealing with uncertainties.

  • Session S: Special Session “Landscape versus local controls on water quality in small streams”

    The Special Session S aims to evaluate the respective role of landscape scale versus local scale processes/structures in controlling water quality in small streams.

    The Special Session S will be chaired by Dr Gilles Pinay, Chair Professor of Hydroecology, School of Geography, Earth and Environmental Sciences, University of Birmingham, UK.

  • Session S-WFD: Special Session “Upscaling from individual ecosystems to groundwater bodies in the light of the Water Framework Directive implementation“

    Interactions between groundwater and associated groundwater-dependent aquatic and terrestrial ecosystems have to be considered in the context of status classification, monitoring and achievement under the Water Framework Directive (WFD). However, lack of scientific insight is often given as reason for not fully investigating these interactions and taking existing knowledge into account within the WFD River Basin Management Plans of different EU member states.

    The Special Session S-WFD aims to:
    a) organize a science-policy interfacing debate between scientists and policymakers about interactions between groundwater and groundwater-dependent terrestrial ecosystems and surface waters under the Water Framework Directive and identify the main implementation drawbacks;

    b) challenge scientists to outline and demonstrate how their research outcomes could be used in implementing this part of the WFD;

    c) evaluate those ideas by a panel of policy makers and the participants of the session. The best ideas will be rewarded and communicated to EU groundwater experts and policy makers (CIS WFD working group on groundwater and DG Environment).

    The Special Session S-WFD will be chaired by:
    - Philippe Quevauviller, Scientific Officer at European Commission and Associate Professor at Vrije Universiteit Brussel, Brussels, Belgium, and
    - Michiel Zijp, National Institute of Public Health and the Environment (RIVM), the Netherlands.
