Аннотация:During field studies in the Lena River Delta in August 2022, water discharges and suspended sediment concentrations were measured with taking samples of water and sediments. The purpose of this research was to study current changes in water flow and water turbidity within the delta, particle size and chemical composition of sediments, the role of local hydrological-morphological and thermal abrasion processes in them, and a comparative analysis of the results obtained with previous studies.
