Abstract
Based on the literature analysis of hypsometric marks of coastal historical and architectural structures, paleoclimatic data and hydrological calculations, it is proved that in the medieval period in the broad sense (400-1800), contrary to the opinions of some researchers, the hypsometric level of Lake Sevan varied only within the absolute limits of 1911-1916m, and its fluctuation amplitude did not exceed 6 meters.The conclusions of the authors of the article coincide with that of A. Markov, dating more than 100 years back, in that the fluctuations of the lake level were exclusively due to climatic fluctuations, and not anthropogenic factors. The possibility of artificial draining of Lake Sevan waters by the arabian conquerors in 699-703 by deepening the bed of the Hrazdan River to capture the island of Sevan is also refuted.
Key words: Sevan, lake level fluctuations, Middle Ages, island, climatic fluctuations, anthropogenic factor.
