Application of GIS-technologies in studying the hydrogeochemical zonation of groundwater (on the example of the Navoi region)

Abstract

One of the most principal issues in regional hydrogeochemistry is the study of hydrogeochemical zonality of groundwater. This phenomenon is manifested in regular and systematic changes in the chemical composition and mineralization of groundwater, varying by geographic area and depth. Understanding these regularities is not just academically significant; it enables critical applications in resource management and environmental protection. By studying the alterations in the chemical composition of groundwater, researchers can elucidate the origins and formation processes of various groundwater systems. Additionally, this knowledge provides valuable insights for the targeted exploration of groundwater sources with diverse compositions. It also aids in predicting potential changes in both chemical composition and mineralization within different geological structures over time. This project encompasses the development of a Geographic Information System (GIS), where selected observation points are mapped, thereby facilitating the construction of detailed layer-by-layer geochemical maps. Such tools are essential for visualizing and interpreting the complexities of groundwater chemistry across the region [1].
