The master's thesis deals with hydrogeological spatial characteristics in the area of Pomurje using the GIS software. I have identified gravel pits in the aquifer and the proportion of evaporation from the water surface where groundwater is present. I have prepared a map of the thickness of the unsaturated layer, a map of groundwater level fluctuations and a map of gravel pits. I performed calculations and statistical analysis of the thickness of the unsaturated layer and the geometric characteristics of the gravel pits. I presented the results in the form of maps, histograms and statistical calculations. The Quaternary alluvial aquifer in the Pomurje area proved to be heterogeneous and anisotropic, as two hydrodynamic types of aquifers occur, an open aquifer in the northwest of the area and an impermeable aquifer in the southeast of the area. The transition between these two aquifer types is gradual, therefore it is defined as a transitional area. The connection between the Mura River and groundwater is active, as it is an intensive exchange of surface and groundwater, therefore the area is defined separately along the Mura River. Gravel pits are located at the top of the aquifer and therefore represent a direct interaction between groundwater and surface and contact with the atmosphere. This in turn poses a pollution risk to an already sensitive aquifer.
