The direction and dynamics of groundwater flow through underground dams are important be- cause they affect their stability. The problems of analyzing the ground water level were solved on the basis of piezometric observations in the body of an earthen dam and by performing Express filling. In total, information was processed for 32 piezometric gates, in which 3 piezometers were installed. As a result of processing in the Ansdimat software package, the dynamics of changes in the ground water level was determined and filtration inhomogeneities were identified. Based on the results of the calculations, it was found that the volume of ground water in the area of the ground dam is 216.9 m/day, which confirms its stable position. This methodological approach can be recommended for creating a diagnostic system for monitoring the filtration regime of ground dams.

Key words: waterworks, the risks of accidents, seepage strength of soils, settlement of earth dams
