Abstract
Results of experimental and methodical works with application of a three-segment technique of Electrical Resistivity Tomography are presented in the message. Measurements are executed on the land and on the water area of the river along one profile by a uniform technique. Field data with maintaining detail, uniform, continuity and depth along the entire profile of observations 1300 meters long are obtained.
The three-segment technique possessing with increased depth of research in comparison with the generally accepted two-segment standard technique is described. The results of the 2D inversion satisfactorily agree with the geological information on the structure of the river valley. By results of the analysis and interpretation of a section of electrical resistivity the main elements of the river valley structure were identified. Information about the properties and geometry of deposits of the of the river valley can be used to construct the initial geoelectrical model, but it is preliminary and requires specification.
