Morphodynamic conditions of particle size distribution of beach sediments of Coastal Area of Karadag Natural Reserve

The article presents the results of studying particle size distribution of sediments in the beach areas of the Karadag coastal area of the Crimean peninsula. In the framework of this study, this area is considered as a lithodynamic system. The paper describes the connection between the granulometric structure of sediments and external processes that affect this system, which is an important indicator of response of the condition of a coastline to dynamic environmental conditions. It is established that the wave processes, exogenous geological processes (mainly of a gravitational nature), abrasion of cliff and bench result in the transportation and accumulation of beach sediments along the coast, as well as determine the peculiarities of their distribution according to particle size distribution. Based on the particle size analysis, the differentiation of beach sediments along the coastline of Karadag is revealed. When calculating the static parameters of the particle size data, the morphodynamic conditions of distribution of sediments in the coastal area are characterized. © Published under licence by IOP Publishing Ltd.
