The article summarizes the results of a comprehensive landscape-archaeological study dynamics human-environmental interaction in Middle Sura region during first millennium AD. data resulted from River floodplain at former confluence and Malaya Sarka. analysis sediments buried soils indicates that period between BC AD saw series climatic cycles changing each other, with periodically being available for various types economic development. Early Iron Age (first – 2nd–3rd centuries AD) formation grey forest part under study. During this period, area remained uninhabited, while population was involved development elevated terraces riverbanks. In contrast, second quarter covered time by broadleaf had most favorable conditions settlement; developed belonged to Volga variant Kiev culture. Their activity gradual deforestation floodplain, meadow landscapes arising instead forest. half 5th century drastic intensification floods an increased runoff. sites assigned represent stage Imen´kovo culture; these were located on terraces. new low flooding dates medieval (8th–13th centuries), bearing traces steppe subsequent floodplain. Later, late early Modern tillage shifted watersheds intensified, accumulation layered alluvial deposits started again, frequent intense taking place. moistening is asynchronous other studied regions Russian Plain, which raises question relationship availability floodplains migration processes.
