Geo-ecological factor of water influence on the relief of steppe zones and semi-deserts of Kalmykia

The Republic of Kalmykia is the only region in Russia with up to 10% of deserts and semi-deserts. Geographically, it is located in the western part of the Caspian lowland. One of the problems of the residents is the lack of fresh water. The aim of the work is to show the influence of the geo-ecological factor on the relief and its connection with surface and groundwater, human health. To solve the problem, results of the expedition routes in Kalmykia were analyzed. Expeditionary and laboratory studies of water resources, express analysis of water, soil and plants was carried out. The decision-making hypothesis adopted a synergistic algorithm for the interconnection system of the water system, the steppe relief and human health. This approach identified that values of the environmental impact are interrelated. Changes in one or several parameters cause instability of the entropy of equilibrium in environmental management. The results can be used to assess the relationship between the relief, water quality, the ecological situation and human health.
