In the TOPSOIL project partners from England, Denmark, Belgium, Holland, and Germany have identified five shared climate adaptation challenges related to the top soil and groundwater :
1. Groundwater flooding in towns and agricultural areas.
2. Saltwater intrusion into freshwater reserves.
3. The need for a groundwater buffer to store excess rain water for later use.
4. Better management of soil conditions, to strengthen the resilience to extreme rain events and improve water quality.
5. An unused capacity to break down nutrients and hazardous pollutants in the uppermost layers
These challenges will be addressed in 16 pilot areas, to develop and test solutions for managing the uppermost 20-30 m of the subsurface. This will lead to a strong improvement of climate resilience in and across pilot areas,
The project aims to improve protection against groundwater flooding, groundwater storage for irrigation and drinking water inland and in coastal areas, and less leaching of nutrients and pollutants along with improved yields. New investigation and management methods will be developed through transnational joint approach techniques, and management will be transferred between the countries. The partnership is strongly committed to bridging science, practice and countries.

The HydroGeophysics Group will use their leading edge geophysical techniques to solve the shared challenges by means of a detailed description of the geology in the upper 30 m. The HydroGeophysics Group is in charge of instrument development as well as carrying out field work with existing methodologies. The instruments to be used include TEM, GCM, ERT/IP, magnetometer and electrical logging. Fieldwork is expected to be carried out in all Danish pilot areas (Varde, Sunds, Horsens and Gedved) as well as pilot areas in international partner countries (Holland and England).
