Objectives and Scope

Many ecological systems owe their existence to physical/chemical properties of groundwater and surface water, and can be damaged if water flow or water properties are changed by anthropogenic or natural processes. The ecological systems may be

  • - the terrestrial ecosystems we see every day, such as the riparian systems along the rivers, and wetlands found in headwaters as well as in low land areas or
  • - the subsurface ecological systems that maintain the groundwater that sustains so many people.

To address the resulting issues, this conference brings together engineers and researchers from engineering and ecological disciplines. The disciplines include, but are not limited to, hydrology, ecology, environmental engineering, biology, chemistry, geochemistry, environmental biogeochemistry, and subsurface microbiology. The unifying theme is the interaction between groundwater and (or) /surface water and ecological systems. A typical example is the hyporheic zone in riparian areas, where the ecological system interacts with water and chemical flows between surface and groundwater.

The goals of the conference are

(1) to provide information that will help that interactions between groundwater, surface water and ecology are better understood, measured, simulated, and managed, and

(2) to improve the technological basis for policy decisions (including WFD implementation) related to the reconstruction of ecologically valuable environments and the use of water resources in these environments.

Focus of HydroEco2011

This conference – HydroEco2011 – has as focus “Pressures and Options”. An important pressure are the global changes, that refer to stresses both from the human activity and from natural changes. The natural changes include the natural climate change. The “Options” refer to the solutions to the problems and needs the society faces with regard to the functioning and quality of ecosystems. The focus “Pressures and Options” is explicitly covered by the planned session “Global change (human activity, natural changes): from noises to trends“. This session will allow to draw your 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.
