Abstract

The spatial distribution of atmospheric precipitation in the basin of the transboundary Zeravshan River and the contribution of precipitation and glacial meltwater to the formation of the river runoff within the Republic of Tajikistan are considered. It has been found that the average integral change in the amount of precipitation in the Zeravshan River basin for the period of 1940–2020 was 20 mm/10 years. The maximum volume of the glacial meltwater in the Zeravshan River fell on the third quarter (June–August) and was equal to 3.11 km³ or 60% of the average annual river runoff, and 0.39, 0.70, and 0.96 km³ of the runoff was formed in the first, second, and fourth quarters, respectively.

降水空间分布及其对塔吉克斯坦泽拉夫山河跨界径流形成的贡献

摘要本文研究了跨界泽拉夫山河流域大气降水的空间分布，以及降水和冰川融水对塔吉克斯坦境内河流径流形成的贡献。结果表明，1940—2020年泽拉夫山河流域降水量的平均积分变化为20 mm/10 a。Zeravshan河冰川融水的最大流量出现在第三季度(6 - 8月)，为3.11 km3，占河流年平均径流量的60%，第一季度、第二季度和第四季度分别形成了0.39、0.70和0.96 km3的径流量。
