Neposhivailenko N. Ecologo-social consequences of sinking of urban territories and development of measures to its decrease (as example Dneprodzerzhinsk taken)

The object of the investigation: ecological and social consequences of ground waters level increase. The purpose: revealing of ecological and social consequences of urban territories and sinking development of technical decisions of reduction of ground waters level (as example of Dneprodzerzhinsk is taken). Methods and equipment: the experimental researches are conducted in laboratory and real (field) conditions, hydro-geological and the social condition is estimated according to archival materials and statistical forms of reporting. Theoretical and practical results: ecological and social consequences of urban sinking are investigated. It helps to solve a topical scientific task of decreasing of harmful environment influence caused by urban territories sinking of. The measures of improving the environmental condition, technical decisions and recommendations on elimination of built up territories sinking are worked out. The novelty: the dependence of the increasing of ground waters level on the properties of alluvial soils and constituents of water balance is established. It allowed to develop the dependence of the alluvial soils obtained in the laboratory conditions filtration coefficient to its meaning in the concrete field conditions; the system of measures on improvement of the ecological condition of Dneprodzerzhinsk water and soil environment scientifically proved; the electronic map of Dneprodzerzhinsk sinking is developed with definition of zones with dangerous levels of ground waters; the ecological coefficients which should bi taken into account while evaluating the influence of sinking on population sickness rate are calculated. Volume of introduction: the practical recommendations for reduction of ground waters level were used in the urban programs on liquidation sinking on the territory of Dneprodzerzhinsk. Sphere of use: municipal economy of Ukraine.
