The preconditions of development of dangerous geological processes connected with intensive subsoil use are analyzed. The theoretical aspects of hydrogeological peculiarities of calculations within the boundaries of urbanized territories are analyzed. It is proved that the further increase of reliability and accuracy of the results of calculations in the first place depends on the improvement of methods for determining the water-physical state of soils and the hydrodynamic peculiarities of groundwater movement. It was established that the anthropogenic component of infiltration feed is the determining factor in formation of water balance of underground hydrosphere in urbanized territories. The methodical approaches to the modeling of complex natural and man-made systems (PTS) are determined. Within the modeling landfills, a wide range of features and patterns of the impact of NWF on the natural environment through the physical fields, hydrogeological and petrophysical characteristics are described. In particular, in the Chornobyl Exclusion Zone an overview of fire prevention technologies with the help of hydraulic structures (GTS) was carried out, a critical level of humidification of peat was determined (62-63%), below which the risk of fires significantly increases. The influence of neotectonic activity on the regime of the underground aquifer of the Neogene plaster of the Dniester basin (in the area of ??the planned construction of the Upper Dnestrovsky cascade of the Hydroelectric Power Plant) is estimated. At the model landfills of the Middle Dnieper, complex investigations of the magnetic parameters of the soil cover were carried out; the efficiency of the use of electrical exploration methods for identification of landslide processes is estimated; the hardware-methodical work is carried out in search of informative parameters for assessing the dynamics of landslide processes, including low intensity. The methods of using remote sensing data (RSZ), primarily vertical movement of the territory, for estimating the intensity of the landslide processes are outlined.5481 Product Description popup.authors Іванік О.М.
