The mathematical modeling of migration of the unsorbed indicator on the way of filtration flow of the first from the surface alluvial-quaternary aquifer underground waters was completed. The imitation modeling was performed to justify the using of isotope or indicator methods to obtain reliable data on aquifer parameters, in particular, the permeability coefficient. Three-dimensional geofiltration model was used and the verification of received predictive results with the results of the field observations was completed. Program complex Visual MODFLOW 2011.1 was used as a tool to manage and edit model and the model’s data, which gave a chance to improve the accuracy and performance of the model while increasing the efficiency of mathematical modeling.
Keywords: mathematical model, water, mass transfer indicator, bromide ion, permeability coefficient, Shelter object.
