In the article the application issues of geographic information technologies and methods of
mathematical modeling of geofiltration and geomigration processes of hydrogeological systems
were discussed, as well as for information support of the groundwater monitoring system. The
object of research are the Akhangaran aquifer, which is a large industrial area with intensification of
agriculture, as well as densely populated, where industrial reproduction of water resources is
established by designing water intake facilities using groundwater, also having huge data on regime,
geological and hydrogeological aspects. The main goal of these researches is to learn the
methodology for assessing groundwater resources by modeling to the GIS basis, theoretical and
applied methods of mathematical analyses.The features are considered and the boundary and initial
conditions are justified. The results are a research technique has been developed to simulate
geofiltration and geomigration processes, to determine the balance of groundwater, and the
hydrogeological parameters of the aquifer have been calculated from it. The calculated values of the
natural resources of groundwater by the parameters of their level mode in the Ahangaran pool
allowed establish the permissible convergence of resource estimates according to the amplitudes of
fluctuations in the level of groundwater and according to geoinformation modeling.
