AP19174932 — Research of colmatation processes on experimental systems of artificial replenishment of groundwater reserves in Southeastern Kazakhstan

Purpose: The research is aimed at studying the processes of colmatation of infiltration basins and evaluating the effectiveness of artificial groundwater replenishment systems.

Relevance: In the conditions of the arid zone of the Republic of Kazakhstan, the problem of replenishing groundwater reserves is critically important for ensuring water resources. The processes of colmatation of infiltration basins directly affect the effectiveness of artificial aquifer replenishment systems. This study makes it possible to evaluate these processes and develop recommendations for improving water conservation efficiency, which is especially important for agriculture and regions with limited water resources.

Scientific supervisor: Doctor of Ph.D., Associate Professor, Ismagulova Aida

Results obtained: The research work involved a comprehensive set of field, laboratory, and numerical studies aimed at investigating surface water infiltration and colmatation layer formation under the arid climate conditions of southeastern Kazakhstan. Field observations were conducted at several rivers, where water and soil samples were collected and analyzed to determine filtration and granulometric properties. Numerical modeling of filtration and moisture transport processes was performed using specialized software, followed by calibration against field data. The patterns of colmatation layer formation and its impact on soil infiltration capacity were identified. Recommendations were developed for the application of artificial groundwater recharge systems, and initial data for the design of infiltration facilities were prepared. The obtained results enable forecasting of groundwater hydrodynamics and improving the efficiency of water supply systems under conditions of water scarcity.
