Energy characteristics for assessing geoecological safety during operation of hydraulic structures

Research objective: assessment of the physical essence of processes and actions necessary for trouble-free operation of hydraulic structures and comfortable use of residential areas; clarification of a number of characteristics of the processes under consideration from the energy point of view. In recent centuries, and especially decades, due to the increasing anthropogenic activity, many natural and man-made structures have emerged. Against the background of always existing natural slope processes, man-made impact has imposed additional characteristics on their patterns. Usually, in the initial stages, anthropogenic impact leads to the activation of undesirable slope processes, and less often to their attenuation during the engineering preparation of the territory at the first stages of development. The energy characteristics of the evolution of these processes are considered, to a lesser extent in natural conditions, to a greater extent within the limits of modern natural and man-made structures, a significant number of which are hydraulic structures. Urban agglomerations, automobile, railway and other communications, agricultural complexes and other vital objects provide for a change in the energy characteristics of slopes within the newly emerging and supplemented natural and man-made structures in the process of evolution. The characteristics of the movement of alluvial deposits within the limits of the technogenically altered beds of small rivers are presented. The path of movement of one of the most undesirable pollutant particles in the geoecological system is considered – an aggregate with heavy metals deposited in it, trapped in the ground due to human activity. The figures shows the movement of the pollutant from the moment of hypothetical entry into the geological environment as a result of human activity to deposition in a thin fraction of sediments of water bodies, a potential barrier to which is usually sediments in the dam zone.
