Methodical recommendations for processing the data of electrotomography are given. Taking into account a priori information, in particular the results of the study of pits, can be carried out by carrying out a limited inversion of the ET data, while it is possible to limit either the resistance of some layers of the model or the position of the boundaries of some layers [1]. In the software used for processing electrical tomography data Res2dinv [2], it is possible to set the boundary of the assumed layer or to limit the resistance of the model section (to introduce local inhomogeneities with a given resistance). But it is difficult to fix the resistance of a particular layer with the available software tools. The proposed approach makes it possible to take into account the parameters of the model built from the pitting data using a preliminary one-dimensional inversion of the electrical tomography data in the Ip2win [1] program, followed by the export of the obtained assumed layer boundaries to the Res2dinv software for carrying out a limited two-dimensional inversion.
