“…The values of the steady-state percolation flow rate were 0.059 dm 3 /min for sandy loam and 0.087 dm 3 /min for sand. Hydraulic conductivity calculated values based on percolation tests were compared with the values calculated according to the empirical equation of Hazen [33,34] (Table 3). This comparison suggests that the greatest difference between the percolated test results and the empirical method for hydraulic conductivity and consequent filtration coefficients is plus 7-8% in sandy, well-permeability sediments, and the smallest difference was found for sandy loam sediments (+1%).…”

The challenge of a good quality drinking water supply to southeastern Kazakhstan’s local population from far-away natural surface water sources motivates groundwater utilization from local aquifers. To prevent groundwater resource deficits, artificial groundwater recharge is needed. To this end, infiltration and clogging processes were evaluated through comprehensive field research in southeastern Kazakhstan’s typical river drainage basin (Aksu experimental site). The infiltration scenario included constructed mini pools and their typical soil profile clogging and silting processes. The local aquifer unsaturated and upper saturated zones underwent a detailed study of water balance, hydrodynamic setting, and filtration properties. The research results suggest that the infiltration rate decreased from 15 m/day until the saturation steady state and remained at 0.75 m/day until the end of the experiment. In summer, clogging layers with thicknesses ranging from 3 mm for the clayey silt layer to 6 mm for muddy clay began to form at the mini pools nearly one month after the test began. During infiltration, the mini pools’ upper soil layer dirt-holding capacity varied from 3.72 to 5.25 kg/m2. The field study results serve as a factual basis for artificial replenishment system design and groundwater replenishment methodology optimization in southeastern Kazakhstan and similar regions.
