The article is devoted to the analysis of the engineering and geological conditions of construction sites for the designed hydraulic structures of the Koksarai counter-regulator, one of the key water management facilities in the Syr Darya River valley. The paper considers the geomorphological features of the area, stratigraphy, lithological composition, physical and mechanical properties of soils, as well as the level and regime of groundwater. A comprehensive assessment of geological and hydrogeological factors influencing the design and construction of spillways, dams, and canals is carried out. Particular attention is paid to engineering-geological zoning and the identification of areas with potential risks, including collapsible, swelling, and saline soils. The results of the study form the basis for sound engineering justification of design solutions and for improving the environmental and technological stability of the structures. In addition, the article presents the results of laboratory studies of soil samples taken from various depths within the proposed construction sites. The features of seasonal fluctuations in groundwater levels and their impact on the stability of structure foundations are analyzed. Recommendations are provided for site engineering preparation and foundation reinforcement, taking into account the specific local geological conditions.
