EU-Interreg-IVb-Projekt CLIWAT (Climate & Water)
Country / Region: North Sea and Baltic Sea
Begin of project: September 1, 2008
End of project: March 1, 2012
Status of project: August 1, 2011
The aim of the EU Interreg IVb project CLIWAT (Climate & Water) is to investigate the effects of possible climate change on areas of the North and Baltic Seas. Currently, various climate studies predict a rise in mean sea level by about 0.5 to 1.5 m by the end of the century. At the same time, climate models predict that increased heavy rainfall can be expected in this region. North and Baltic Sea coast would be particularly affected by such scenarios, notably the regions, which are scarcely above or just below mean sea level now.

For the investigation six strategic areas were selected by the project partners (http://cliwat.eu/). In four areas the present status of groundwater and salinity in the soil structure by invading sea water was determined with the helicopter electromagnetic system (HEM) of BGR. The obtained 3D data sets (134: Vojens [Southern Jutland, DK], 135: Schouwen [Zeeland, NL], 136: Perkpolder [Zeeland, NL], 137: Friesland [Northern Friesland, NL]) are used for modeling the respective groundwater structures. The modeling work is carried out by groups in the Netherlands and Denmark. The BGR is responsible for ensuring that the HEM data can be optimally utilized there. The results of the performed surveys carried out in summer of 2009 conducted with the BGR helicopter are described in four technical reports. The general CLIWAT project results are published in a "Special Issue" of the journal "Hydrology and Earth System Sciences" (HESS) and are also presented on the final conference in Aarhus (DK) on January 5th, 2012 (Conference).
