Abstract
The deterministic method of mathematical modeling for predicting the development of hydrogeological processes in space and time under the influence of natural and anthropogenic factors is of the greatest interest. The implementation of the finite difference method in hydrogeological modeling is most often carried out using the well-known Processing Modflow software package. The determination of hydrodynamic heads at the stage of epignosical modeling plays a key role in improving the accuracy of predictive hydrogeological modeling. The underground water table surface is adjusted mainly by refining the values of geofiltration parameters, infiltration feeding intensity or flow rate. The coincidence of field and model results of hydrodynamic head determination at a limited number of points is usually a criterion for modeling accuracy.
To increase the reliability of the spatial location of the undergroundwater tabel surface, the authors recommend using the standard Darcy Flow module of the ArcGIS software package. The geofiltration deterministic model created in this way can be used in the predictive modeling of groundwater flow, which corresponds quite accurately to real conditions. The calculations confirm the feasibility of the integrated use of the Darcy Flow module in the ArcGis environment and the Processing Modflow software package. This approach allows to significantly optimize the process of practical application of the deterministic finite difference method in modeling groundwater flows using engineering and geological survey data and to increase the reliability of the geofiltration deterministic model.
