Abstract
The article discusses the results of geophysical studies aimed at improving geoinformation support for groundwater monitoring near large anthropogenic objects to minimize their environmental impact. The effectiveness of geoelectrical methods in studying the engineering-geological condition of the southern Kryvbas region and the influence of the technosphere on its hydrogeological environment is demonstrated. The active exchange of anthropogenic waters contributes to the development of karst processes, which, in turn, cause additional changes in the surface level of the first aquifer. Due to the presence of mosaic groundwater discharge zones into crystalline rocks and karst formations, a continuous flooding zone is absent.
The analysis and interpretation of geological and geophysical information indicate the impact of Precambrian basement fault tectonics on the hydrodynamics and geofiltration of groundwater in the sedimentary cover. A correlation assessment between water levels and the morphology of geoelectrical resistance anomalies provided qualitative and quantitative data that align with observations from the network of monitoring hydrogeological wells. The correlation results also indicate a variable nature of the neotectonic structure of the sedimentary cover and crystalline basement in the study area, influencing the hydrodynamics of geofiltration and geomigration of groundwater.
Based on the interpretation results, a constructed map illustrates the depth marks of the first aquifer from the surface, whose structural features determine the direction of underground water filtration—toward the west, in the northern and central parts of the area, in the direction of the Inhulets River.
