Filtration and geoelectrical investigations in the karst region of North Lithuania
Petras KLIZAS, Rimantas ŠEČKUS

Water flow through sandy-clayey glacial sediments and weathered sulphurous-carboniferous rocks and their geoelectric parameters were investigated for estimating the intensity of karst processes and possible pollution of groundwater in Northern Lithuania. The modified Nesterov–Boldyrev infiltrometer and the Lita-5 permeameter were used for measuring the permeability. The construction of the
instruments and the methods of measurements were elaborated at the Department of Hydrogelogy and Engineering Geology of Vilnius University. The geoelectric survey was done using electrical tomography, one of the newest geophysical methods.

Keywords: karst development, infiltration, permeability, modified Nesterov–Boldyrev infiltrometer, electrical tomography, electric resistivity rocks
