Construction of the Geofiltrational Model of a Stone–earthen Dam Based on the Geophysical Data

The numerical filtration model of the stone-earthen dam is constructed as a result of the joint analysis of the self-potential electric fields, electrical and seismic tomography, and piezometric observations. The model allows to obtain a distribution of piezometric surface in the dam body and to predict the occurrence of erosion. This complex of geophysical methods may be recommended for continuous monitoring in the period of maximum strain on the dam
