Granulometric features of the detrital material of modern beaches of Sevastopol

The history of studying the granulometric composition of the detrital material of the beaches of Sevastopol in scientific publications from the middle of the twentieth century to the present is considered. The granulometric characteristics (quartiles, median diameter, and sorting coefficient) of sediments from natural unofficial beaches of Sevastopol located in the bays of Sevastopolskaya, Karantinnaya, and Kazachaya have been calculated. Cumulative curves and diagrams of the granulometric composition of beach sediments have been compiled. The analysis of the general features of the granulometric composition of beach sediments in the bays and their distribution according to the profile of the studied beaches is carried out. Differences in the size and degree of sediment sorting on beaches located in different parts of Sevastopol bays have been revealed. The factors determining the main granulometric characteristics of the detrital material of modern beaches of Sevastopol are identified. Beaches are typified according to the size composition of the dominant fractions.
