Sapuzhak O. Mathematical modelling by boundary element technique in geoelectrometric three-dimensional problems

The dissertation is devoted to developing methodology, algorithms and software for solution of geoelectrometric three-dimentional direct problem with curvelinear boundaries of medium division and arbitrary profile of day surface relief using boundary element technique. The software realizing boundary element technique for geoelectic field calculation in the case of conducting and non-conducting inclusions and arbitrary shapes of relief is created. The estimation of software accuracy for curvelinear boundary approximation and electrical field calculation is done. The possibilities and perspectives of real geoelectric section modelling on the examples taken from the practice of electrical prospecting investigation of additional raw reserves for Dolyna salt-extracting plant in the Precarpathians and electrometric monitoring of Czorsztyn-Niedzica dam in Poland are shown.
