摘要：The article describes the definition of filtration flow gradients in the dam's body on the example of the Kattakurgan reservoir, the analysis of the reasons for their change in cross-section. Evaluation of the aggressiveness of the filtration flow in the dam's body plays an important role in ensuring the stability of the reservoir dam and its parts. To assess the aggressiveness of the filtration flow in the dam's body, it is necessary to know the action pattern of the filtration water in the reservoir dam and its effect on the elements of the dam. In addition, the chemical composition of the water in the piezometers was analyzed in the laboratory to determine the aggressive effect of sulfate elements on the piezometers and their corrosion. Measures on the observations of systemic piezometers were also mentioned.
