    Abstract. The article presents the data of field, laboratory and theoretical studies, which made it possible to determine that processing, abrasion destruction of natural shores and loose upstream slopes of dams and enclosing structures, takes place on technological water bodies of Belarus - regardless of their economic use - technical, drinking water supply, regulation of runoff, energy, land reclamation, etc. The period of development of the processing process and the formation of the equilibrium profile is divided into a number of time periods (stages). Three stages are distinguished for the conditions of water bodies in Belarus: initial, intense dynamics and attenuation (equilibrium). Based on the data of field surveys of shore protection structures, the current state of various types of fasteners is assessed with the identification of the causes of their destruction and the extent of deformations. It has been established that the most common shore and slope fastenings are fastenings in the form of reinforced concrete monolithic or prefabricated plates. It is determined that the most widespread are the deformations of the fastenings in the form of the disclosure of inter-tile construction, temperature and settlement joints. As a result of opening the joints of the plates, the destruction and washing out of the sand and gravel bed, the formation of hollows and niches in the body of the slope with its subsequent processing, deformation and destruction of the fastening take place. It should be noted that the destruction of the fastening also occurs in stages, and the stages of the destruction of the fastening coincide with the staging of the processing of loose ground slopes. Based on the data of full-scale and experimental laboratory studies, scientifically substantiated criteria for assessing the stability of soil slopes and slopes with fastening by reinforced concrete slabs are proposed, which can be used to predict the state of designed and operated shore protection structures and fastening slopes. An enlarged methodology has been developed for assessing the risks abrasion of coasts and slopes of retaining structures based on the proposed territorial coefficient of abrasion risk, a mathematical factor model of risk based on the fault tree, and also an experimental electronic map of the risks of abrasion for the conditions of water bodies in the Minsk region of Belarus are developed.
    Key words: technological reservoir, reservoir, slope fastening, deformation, abrasion, coastal protection, stability criteria, territorial risk coefficient from abrasion, risk map.
