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.
利用水同位素组成特征评估开阔水域期间冬季和夏季降水对上奥布径流的影响
摘要 通过对一年中寒冷和温暖季节河水和大气降水中的稳定同位素（2H、18O）进行为期三年（2020-2022 年）的研究，评估了它们对上奥布低地地区河流径流的贡献。尽管降雨量超过降雪量（占全年降雪量的 2/3），但研究表明，融雪水在整个开放水域期间对河流径流的形成贡献很大：根据一年内降雪和降雨的比例，从 42% 到 61%不等。
