The purpose of the project:

Scientific substantiation of the creation of circulating systems, artificial aquifers using the methods of infiltration and accumulation with the capture of flood, temporary, descending and drainage waters formed in the valleys of rivers crossing the foothill plain.

Program objectives:

1. Scientific substantiation, development and assessment of the prospects for using technology for replenishing groundwater reserves through infiltration of flood, groundwater and wastewater, intermittent streams into non-confined aquifers lying near the surface.
2. Substantiation and implementation of the method of accumulating river flow of flood waters into melt water storage ponds with their subsequent use for the needs of the agricultural sector. Research of the prospects and technical capabilities of artificial replenishment of reserves due to gravity infiltration involves flooding a diked area, installing special basins with a dense network of small canals, and using the beds of permanent and intermittent streams.
3. Development of technology for the creation and implementation of sub-irrigation systems based on the integrated use of non-traditional irrigation sources under water resource shortages caused by the climate changes.
4. Scientific substantiation, development and assessment of the prospects of using modern irrigation systems, water-saving technologies in experimental areas of agricultural development with the introduction of non-traditional irrigation sources.
5. Hydro-geo-ecological monitoring support for the implementation of the Program objectives to ensure safe methods for the integrated use of irrigation and groundwater on irrigated lands.
6. Development of an electronic GIS database of technologies of the obtained research data based on the creation of physical and development of computer models of an experimental system for the accumulation of river flows of flood waters in storage ponds.

Attracting additional water resources for irrigation from local sources will increase the reliability of irrigated agriculture in small agricultural settlements without the cost of building centralized irrigation systems through the most efficient use of local runoff and groundwater, when depending on soil, hydrological conditions and terrain.

A significant reduction in irrigation water losses and a decrease in the volume of mineralized drainage flow will contribute to the improvement of the ecological and reclamation state of irrigated lands and the source of collector and drainage water discharge.

EXPECTED AND ACHIEVED RESULTS: - 2024 ye.

The analysis of factual data, publications and analytical materials based on domestic experience in artificial replenishment of groundwater reserves and circulating water use systems was carried out; A field survey of the work area was carried out. An experimental site has been selected for scientific research. 5 monitoring wells have been drilled. Hydrogeological parameters of the aquifer were obtained. The wells are equipped with Solins loggers with the ability to remotely measure the level and temperature of groundwater. 7 samples of surface water and groundwater were tested.

Laboratory studies were carried out on 7 samples of surface water and groundwater water. The chemical indicators of the selected water samples were analyzed for the suitability of their use for irrigation.

A regime network consisting of 5 wells has been created to study the level and temperature of groundwater, as well as to monitor the level and salt regime of groundwater and assess the impact of various anthropogenic and natural factors on groundwater.

Topographic survey was carried out using the DJI Mavic 3M UAV and the DJI D-RTK 2 mobile base.

Water-energy-saving environmentally friendly technologies for the integrated and effective use of flood, collector-drainage and groundwater, local runoff on irrigated lands of the Enbekshikazakh district of the Almaty region will be developed and recommended by agricultural producers for implementation.
