Multi-year variability of organic matter content in water of Rybinsk reservoir

摘要

This study of the Rybisk Reservoir tributaries and stretches investigates the content of organic matter during the years of medium water level (1981-1982) and evaluates the contribution of selected components in its total amount. In 2000-2007, organic matter content has been monitored in the Tsentralnii and the Volzhskii reaches occupying the major of the reservoir area, and annual and seasonal dynamics of organic matter content in the reservoir has been tracked. High correlation between the organic matter indices and the annual flow has been shown. This suggests that the latter plays a predominant role in the formation of the total organic matter content.
