The general purpose of real-time monitoring of the technical condition of hydrotechnical structures of reclamation systems is to detect the deterioration (deterioration of the condition) of the degree of physical wear and tear, the reasons that entail the deterioration of condition, a decrease in efficiency of the structure. Materials and methods. The studies carried out were based on general scientific methods: descriptions, comparisons, statistical analysis, systems approach and economic and mathematical modeling. The objects of diagnostics of the technical condition of the hydrotechnical structure of the reclamation water complex include: dams, hydroelectric power plant buildings, spillways, drainage and water outlets, tunnels, canals, locks, piezometric systems, power units, perimeters of the hydraulic system, bridges, foundations. Results. It has been determined that the control of the state indicators on most hydraulic structures is carried out visually and with the help of control and measuring equipment, mainly by destructive methods, manually. The high potential of the process of automation of operations of technical diagnostics of the structures of the reclamation water industry complex has been revealed. The modern complex information systems used in the advanced sectors of the economy of Russia and the world are characterized. Possibility of qualitative improvement and development of the system of automated technical diagnostics of hydraulic structures due to the priority use of modern achievements of information technologies is presented. Conclusions: the developed methodology makes it possible to improve information technologies for diagnostics of hydraulic structures, the reasonable use of such a system establishes the duration of the safe operation of hydraulic structures, reduces operating costs during the period of use and with a negative impact on the environment, and creates new information systems that allow managing hydraulic structures.
