Development regularities of plain reservoir shore marginal erosion

The problem of intensified marginal erosion of lowland reservoir shores is relevant today, since settlements, agricultural lands, forests and industrial enterprises fall into the danger zone every year. The current situation in the field of studying the marginal erosion of reservoir shores requires to improve the existing methods and to create new ones. The purpose of the study performed is to identify the most significant factors and conditions that determine the intensity of the marginal erosion of reservoir shores. The research involves collection and analysis of data from previous studies, field observations of the Volgograd reservoir shores, a survey of the local population regarding the manifestation and activity degree of marginal erosion, as well as engineering and geological zoning of the coastal area. E.G. Kachugin and N.E. Kondratiev’s methods for calculating the total energy of waves are applied. The obtained results have been processed using the methods of mathematical statistics. The subject of the study is marginal erosion of the reservoir shores, the object of the study is the coastal area of the Volgograd reservoir. The main development patterns of marginal erosion of the Volgograd reservoir shores have been identified and the factors influencing this process (condition factors, process factors) have been specified. The simplest temporal patterns of the marginal erosion process are presented in the form of a kinematic model. According to the calculation results, which are based on the correlation analysis, the wave energy, water level fluctuation, and the erosion index of rocks composing the coastal slope had the greatest impact on the process of marginal erosion of Volgograd reservoir shores. The data obtained during the study will be used for further modeling and forecasting of the marginal erosion process of the Volgograd reservoir shores.
