A article developed a mathematical model for monitoring and predicting changes in groundwater level and salt concentration, as well as for representing the process of flooding, salinization and waterlogging in the design of hydraulic structures. A qualitative analysis of the research work on this issue is presented. Since the process is represented by a nonlinear differential equation, a numerical algorithm based on finite-difference schemes was developed to solve it. Mathematical models of the processes of geofiltration of salt migration have been improved and computational algorithms have been developed. A numerical algorithm has been developed for calculating the problem of changing the groundwater level, taking into account active porosity, flow rate in two-layer formations.
