Zaporozhets The use of modern methods for complex studies of the hydrotechnical structures of the Barents Sea region The Barents region hydrotechnical structures (HTS) as part of the bulk earth dams and levees tailings of mining enterprises in terms of requirements of the responsible entities have been considered. The brief review of emergencies and accidents of HTS with an analysis of their causes and geo-ecological consequences has been fulfilled. The necessity and urgency of the application of modern techniques for comprehensive research and monitoring of the HTS state have been shown: geo-fluid mechanics computer modeling, subsurface georadar sensing, GPS geodetic measurements, optical and radar satellite imagery. Joint use of GPR and satellite imagery in combination with traditional engineering-geological, hydro-geological and geodetic studies allows obtaining a more complete picture of the HTS state taking into account local and regional geological and fluid dynamic processes. The system structure of HTS complex researches which creates a scientific and technical basis for researching the geologic-geophysical environment, shifts, deformations and power influence has been developed. This allows to reveal the hidden filtration and deformation zones in HTS at early stages of their formation and in due time to make the administrative decision on prevention and localization of any emergency. Application of modern methods for HTS complex researches will allow to receive operational information on their state, parametrical sizes of volume, angular and linear deformations and movements, intensity of natural and technogenic influence. The obtained data have to be integrated in the "Database and Parameters" geoportal by means of which their logical processing and comparison to standard and extreme values has to be carried out. On this basis expert assessment of the current and expected state of HTS is carried out and the operating decisions including on development, in case of need, of preventive and protective measures are made. Key words: bulk earth hydrotechnical structures, tailings, georadar, modern techniques.
