GEOELECTRICAL IMAGING OF HYDROGEOLOGICAL CONDITIONS OF THE COASTAL ZONE OF WOLIN ISLAND

Abstract. The article discusses the problem of complex hydrogeological conditions in the coastal zone of Wolin Island in Poland. Hydrogeological situation of the island was imaged by geoelectrical methods. Groundwater of the coastal zone is in constant contact with the saline sea waters. This fact constitutes a threat of groundwater degradation and has an influence on the methods of groundwater protection. The resistivity of Quaternary permeable and impermeable deposits is significantly different in areas where groundwater is characterized by low values of total dissolved solids (TDS). This implies that hydrogeological classification of the results obtained from electrical resistivity tomography (ERT) is not difficult. In the study area, the situation is completely opposite and much more complicated because of salty sea water ingress into aquifers. This affects the resistivity values of permeable and impermeable deposits, obtained from geophysical tests.
