Interpretation of the results of experimental filtration work using the mathematical modeling method to justify the parametric base of the numerical geofiltration model

The purpose of this research is to substantiate the parametric base of the mathematical model of a multilayer system consisting of hydraulically coupled aquifers. The article analyzes the results of the interpretation of pumping out using analytical methods. It was found that their use in complex hydrodynamic conditions simplifies the schematization of the work area. This makes the obtained hydrogeological parameters highly generalized. The most effective way to determine all geofiltration parameters is to reproduce the experience on a groundwater flow model. The article describes the structure of the numerical model created on the basis of the Processing Modflow package (v.8.0), the technique for interpreting the pumping using numerical simulation, the comparative characteristics of the parameters obtained as a result of numerical and analytical processing, and the main results.
