Mapping of the north-eastern part of kozłowicka buried valley based on geoelectrical data

The pa per is aim ing to de ter mi nate the ex tent of the north east ern arm of Koz³owicka bur ied val ley on the grounds of own re search by means of elec tri cal re sis tiv ity to mog ra phy – ERT and avail able ar chi val re searches. On the Hy drogeo log i cal map of Po land, ¯yrardów sheet (Felter and Nowicki, 1998a, b) Koz³owicka bur ied val ley was dif fer en tiated as an in di vid ual hydrogeological unit. The re sults of the anal y sis show that the ex tent of the struc ture, de fined by its up per bound ary, dif fers sig nif i cantly from the one sug gested on the sheet of Hydrogeological map of Po land. Since there was no data avail able in the north east ern part of the dis cussed arm of Koz³owicka bur ied val ley, the north ern bound ary was de fined only based on avail able geoelectrical sound ing pro files (Czerwiñska, 1988; Topolewska, 2015). In or der to con firm sug gested so lu tion, geoelectrical re search by means of elec tri cal re sis tiv ity to mog ra phy (ERT) was con ducted. The mea sure ments were per formed along 3 pro files lo cated in the area of in ter est. The au thors would like to point out the need of the us age of ERT in map ping and study ing bur ied struc tures that might be ground wa ter res ervoirs. As a re sult, one ob tains quasi-con tin u ous im age of elec tri cal re sis tiv ity of the subsurface. Due to the con trast of elec tri cal prop er ties of sed i ments, it is pos si ble to de ter mine up per and bot tom sur faces of bur ied struc tures, formed within gla cial de pos its.
