5. Lagutin Evgeny Ivanovich on the topic: Regularities in the formation of underground runoff of the inland orogens of Central Asia defended by the Doctor of Geological and Mineralogical Sciences in 2015 by specialties: 25.00.07 - Hydrogeology; 25.00.08 - Engineering geology, permafrost and soil science. Purpose. Geo-hydrological assessment, typification, forecast of underground flow and georisks caused by them based on the development of a new scientific direction "Geohydrology".
The results and novelty: the thesis is devoted to geohydrological analysis, assessment, prediction and typification of underground runoff and georisks induced by them in the territory of the inland continents of Central Asia (Kyrgyzstan, Tajikistan, Uzbekistan, Kazakhstan). The foundations of the new scientific direction "Geohydrology" are developed on the example of the inland continents of Central Asia. The position and role of underground runoff in the general zoning scheme of the underground hydrosphere (geohydrothermal, geohydrochemical, geohydrodnamic) is substantiated. The mechanism of natural underground flow formation was revealed in the inland orogens of Central Asia.
Geohydrodynamic systems of the underground hydrosphere are divided into three hydrodynamic zones: the upper is the active water exchange zone, the middle is the difficult water exchange, and the lower one is the stagnant water regime. The upper hydrodynamic zone of the underground hydrosphere is a set of basins of underground flow, separated by underground watersheds. A logical-mathematical model of geo-hydrological conditions for the formation of underground flow on the basis of finite-difference equations and a matrix form for presenting the results of the calculation of natural groundwater resources have been developed. A method for calculating the natural resources of groundwater with a given degree of security is proposed. New forecast maps were compiled: “Geohydrological typification and prediction of underground flow” and “Engineering-geonomic assessment and forecast of georisks” for the studied areas. For the first time, geohydrological stratification boundaries, geohydrodynamic systems and the corresponding basins of underground drainage identified in the hydrosphere of the inland orogens.
Scope and recommendations: Hydrogeology, engineering geology, geohydrology, problems of sustainable and environmentally safe water supply to the developing countries of Central Asia.
