Purpose: to develop a nomenclature of processes identified during monitoring and inspection of the technical state of reclamation hydraulic structures (HS), for the uniformity of entries in record books.
Materials and methods. The object of the research was the processes occuring in reclamation systems, such as: hydraulic and related processes of erosion, abrasion, vibration, filtration phenomena and soil suffusion processes, deformations of a structure and its elements, defects and damage to structures and their elements. When conducting research on these processes and detecting hazardous phenomena, a search and analysis of technical, regulatory-technical and regulatory documentation as well as current developments in the field of observations of hydraulic structures and their surveys was carried out.
Results. As a result of the work, a recommended schematic pattern of the nomenclature of processes and phenomena for open-flow structures and pipeworks was proposed, with a definition of their hazard degree and assignment of a code with three hazard groups: the least dangerous (calculated), dangerous, and very dangerous. The processes that can occur during local deformations in the earthen and concrete parts of structures (dams, dikes), during filtration through concrete structures, and the reasons for their formation are considered.
Conclusions. To determine the top-requested for repair or reconstruction objects, it is necessary to have the latest information on the technical condition, which makes it possible to calculate the scope of work for the subsequent calculation of the priority of capital investments and the adoption of appropriate decisions objectively and differentiatedly. To reduce labor intensity, a procedure for visual observations with certain rules for examining and fixing the harmful effects on structures, manifested due to their defects, and their nomenclature has been developed. A list of processes that occur during local deformations in the earthen and concrete parts of structures, seepage through structures, with possible reasons for their formation, is also proposed.
