Modeling of hydrogeological processes in irrigation areas based on modern programs

This article uses modern modeling systems to assess the impact of intensive irrigation on the state of groundwater and the rocks of the aeration zone. In doing so, existing ideas about aquifer recharge, flow, consumption, and changes in groundwater quality were considered, studying these areas' hydrogeological and reclamation hydrogeological conditions. Groundwater balance analysis was performed based on the results of solving the inverse non-stationary problem for total groundwater deposits. The correspondence of underground water at control points during this period (results of regular observations of Kashkadarya GGS) and underground water seeping into the collector-drainage network in natural and model conditions was observed. According to the research results, renewable (flowing) underground water reserves in the general balance are 15671-2476 = 13195 m 3 /day, while the indicators of consumption and saturation of underground water reserves are equal to 2476 and 8915 m 3 /day. It was proved based on the results obtained with sample solutions to the problem, taking into account the rise or fall of the level of underground water in different parts. The article determined that the accumulation of underground water reserves in the region is mainly due to the increase of infiltration in newly developed lands. At the beginning and end of the modeling period, the depth of the groundwater table was shown using maps and marked with numbers.
