Buried valleys, or – more correct – buried Pleistocene subglacial channels, are in the interest of geoscientists since their discovery more than hundred years ago. For more than thirty years their groundwater occurrence is known and becomes increasingly of interest for the water supply. The main reason is that deep reservoirs are generally better protected to pollution than near-surface aquifers.
The project BurVal (www.burval.org)
has been established to study systematically buried valleys of the North Sea Region. The BurVal Working Group was constituted during a workshop on buried valleys, held in Flintbek in September 2001. A project application was submitted to the Interreg North Sea Programme Secretariat in September 2003 and the activities of BurVal started January 2004. Since then intensive investigations have been conducted in six pilot project areas that would not have been possible without the co-funding by the European Union. The transnational aspect allowed the possibility to test and compare a wide range of methodologies.
The aim of the project BurVal is to develop tools for the mapping of buried valleys under the aspect of the groundwater supply, to test and demonstrate these tools at selected Pilot project areas, and to show how these mapping results can contribute to a sustainable use of the water resources.

The project areas are:
1 Bording Valley, investigations coordinated by Ringkjøbing Amt
2 Tyrsting Valley, investigations coordinated by Vejle Amt
3 Rødekro Valley, investigations coordinated by Sønderjyllands amt
4 Ellerbeker Rinne, investigations coordinated by LANU and BSU
5 Cuxhavener Rinne, investigations coordinated by GGA
6 Groningen Valley, investigations coordinated by TNO.
BGR activities took place in four survey areas: Tyrsting Valley (DK), Groningen Valley (NL), Ellerbeker Rinne (D), and Cuxhavener Rinne (D).
The results and findings of the project are presented in a handbook:
BurVal Working Group, 2006. Groundwater Resources in Buried Valleys – a Challenge for Geosciences. Leibniz Institute for Applied Geosciences, Hannover.
The project has been part-financed by the European Union.
