Abstract
The results of three-year (2020–2022) studies of stable isotopes (2H, 18O) in river water and atmospheric precipitation in the cold and warm seasons of the year were used to assess their contribution to river runoff in the lowland area of the Upper Ob. Despite the predominance of rain over snow precipitation (up to 2/3 of the annual amount), it was shown that snowmelt water contributes much to river runoff formation throughout the open-water period: from 42 to 61%, depending on the proportions of snow and rain that fell within a year.
期刊介绍:
Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
