ГИДРОХИМИЧЕСКОЕ СОСТОЯНИЕ ВОДНЫХ ОБЪЕКТОВ НАЦИОНАЛЬНОГО ПАРКА ВАЛДАЙСКИЙ

Specific features of the regime of the Borovno-Razliv lake-river system are investigated, as well as the mechanism of the flow of dissolved mineral and organic substances and exchange processes between bottom waters and soil during different seasons within theterritoryofValdainational park. The actual hydroecological state of water objects is considered taking into account specific conditions of nature and water management in the region. The results of investigations made it possible to suggest the optimum terms of further observations on the lakes of the Borovno-Razliv system and other lakes of the national park.
