Mapping of the north-eastern part of Kozłowicka buried valley based on geoelectrical data
Journal Title: Studia Quaternaria - Year 2016, Vol 33, Issue 2
Abstract
The paper is aiming to determinate the extent of the northeastern arm of Kozłowicka buried valley on the grounds of own research by means of electrical resistivity tomography - ERT and available archival researches. On the Hydrogeological map of Poland, Żyrardów sheet (Felter and Nowicki, 1998a,b) Kozłowicka buried valley was differentiated as an individual hydrogeological unit. The results of the analysis show that the extent of the structure, defined by its upper boundary, differs significantly from the one suggested on the sheet of Hydrogeological map of Poland. Since there was no data available in the northeastern part of the discussed arm of Kozłowicka buried valley, the northern boundary was defined only based on available geoelectrical sounding profiles (Czerwińska, 1988; Topolewska, 2015). In order to confirm suggested solution, geoelectrical research by means of electrical resistivity tomography (ERT) was conducted. The measurements were performed along 3 profiles located in the area of interest. The authors would like to point out the need of the usage of ERT in mapping and studying buried structures that might be groundwater reservoirs. As a result, one obtains quasi-continuous image of electrical resistivity of the subsurface. Due to the contrast of electrical properties of sediments, it is possible to determine upper and bottom surfaces of buried structures, formed within glacial deposits.
