ASSESSMENT OF NATURAL GROUNDWATER RESOURCES AND HYDRODYNAMIC AND HYDROCHEMICAL REGIMES OF THE AKHANGARAN BASIN
Abstract
This article examines changes in the groundwater regime of the Akhangaron basin, as well as patterns of formation and development of hydrodynamic and hydrochemical aspects under the influence of various factors. As part of the research, an analysis was conducted on the geological and hydrogeological conditions of the basin, including groundwater recharge sources and discharge areas, as well as the characteristics of groundwater occurrence and distribution. The assessment of natural resources was carried out using methods of hydrogeological zoning, water balance calculations, and analysis of long-term observations of groundwater level regimes. Special attention was given to studying the hydrodynamic parameters of aquifers, including hydraulic conductivity coefficients, specific yield, and groundwater flow directions. Hydrochemical analysis allowed for the determination of mineralization, ionic composition, and spatial-temporal variability of groundwater quality, as well as the identification of natural and anthropogenic impact factors. The main types of groundwater were classified according to their chemical composition, and their suitability for domestic drinking water and agricultural water supply was assessed. The obtained results can be used in the development of measures for the rational exploitation and protection of groundwater resources in the basin.
