Subject of research: alluvial-proluvial covering deposits and top coating of water-bearing rocks of water bed when researching artificial ground water spreading processes (hereinafter referred to as AGWSP) in the boundary conditions of the open infiltration basin physical model by the example of the Karatal area of experimental studies in the South-East Kazakhstan Goal of research: holding the complete set of field works on engineering geology and mechanics of aeration zone ground soil in the physical model of a mini basin with infrastructure of water intake and captation facilities imitating in small the optimal system of AGWSP for this region, which are determining and major criteria when designing open infiltration facilities. Methodology: scientific innovation, instrumental, systematic approaches when studying and giving detailed characteristics of hydrophysical, hydro-dynamic, and filtration properties of covering deposits and top coatings of water-bearing rocks of water bed as a part of AGWSP processes studies. Researching theses parameters as a part of AGWSP processes studies is based on up-to-date technological approaches of the world practice to this issue. The research has been held on a specially arranged unique pilot site of the system in the boundary conditions of the open infiltration basin physical model with the use of state-of the- art diagnostic units and laboratory equipment. Research relevance : the paper represents organization, methods, results of newly held field studies of hydrophysical, hydro-dynamic, and filtration properties of covering deposits and top coatings of water-bearing rocks of water bed on a real object and for real conditions of the South-East Kazakhstan. To find necessary parameters that characterize these properties when holding studies a unified approach wherein the natural conditions of water seepage to the complete saturation of tested thickness of rocks of covering deposits with due account for spreading of hydrodynamic water in the context of ground water level close bedding was taken. Studies were held individually by each uncovered genetic horizon of alluvial-proluvial covering deposits and the upper section of water-bearing rocks of water bed. Results: specific characteristics of specific gravity, natural humidity, maximum molecular moisture capacity of other hydrophysical and filtration properties of rocks under the real conditions of artificial extra groundwater recharge for public water supply of a rural community are obtained. Detailed field characteristics of hydrophysical properties of rocks of covering deposits in the bases of infiltration basins as well as estimation of their impact on the processes on mudding can be recommended and taken as estimate indicators both on the stage of feasibility study and detailed engineering of AGWSP processes without additional time-consuming and costly research works.
