G.S. Borodulina. Role of groundwater flow to lakes of the onega watershed in formation of the chemical composition of lake water // Transactions of Karelian Research Centre of Russian Academy of Science. No 4. Northern Water Problems. 2011. Pp. 108-115
Keywords: groundwater, Onega watershed, chemical composition, groundwater flow, chemical balance.
The hydrogeological conditions for formation of groundwater flow in the Onega catchment are characterized. Water and salt groundwater flow directly to Onega and some lakes of the Shuja River basin (Syamozero, Kroshnozero, Suojarvi, Pryazhinsky) avoiding the river network was quantified. We found that the share of direct groundwater flow in the lake water balance is insignificant, however its influence on the chemical composition of the lake water is more significant and comparable with that of the river discharge. The role of direct groundwater flow in the chemical balance is most important in small lakes.
