The Transfer Impedance of Capacitive Electrodes and Insulated Wires on the Ground Surface
ОПЫТ КОМПЛЕКСИРОВАНИЯ ГЕОРАДАРА И ВЫСОКОРАЗРЕШАЮЩЕЙ ЭЛЕКТРОТОМОГРАФИИ В ЛАНДШАФТНЫХ ИССЛЕДОВАНИЯХ
Ground-penetrating radar and electrical resistivity tomography (ERT) are often used in combination. Still, a rational integrative survey using these methods is possible in shallow depths (0-20 m) using high-resolution ERT with electrode spacing not exceeding 1 m. In this paper, we present the results of such an experimental integration for studying boundaries between landscapes, which are indirectly related to differences in the composit ion of the underlying rocks.Еорадиолокация и электротомография часто применяются в комплексе, однако необходимо понимать, что рациональное комплексирование этих методов возможно в области малых глубин (0-20 м) при использовании высокоразрешающей электротомографии с шагом между электродами не более 1 м. В настоящей работе мы приводим результаты такого комплекса методов применительно к поиску границ между ландшафтами, которые косвенно связаны с различием состава подстилающих пород

DC Resistivity Studies of Shallow Geology in the Vicinity of Vistula River Flood Bank in Czernichów Village (Near Kraków in Poland)
DC resistivity methods, soundings and Electrical Resistivity Tomography, were applied to study shallow geology in the
place of planned construction of an experimental flood bank. The geoelectrical surveys provided quantitative information about the
spatial presence of the various geoelectrical/geological layers: alluvial soils, sands, gravels and clays. ERT allowed maps to be constructed
showing subsurface structure. A combination of geoelectrical and geological information resulted in a much better identification
of the geological structure
