Abstract

The current (2015–2017, the period for which necessary datasets were available) changes in the annual flow of the Moskva River under the influence of anthropogenic and climatic factors are considered. They are compared with the period of annual normal flow calculation. The anthropogenic impact on runoff is also estimated in comparison with the middle of the 19th century and with 1960s–1980s (the period of the greatest anthropogenic load on water resources). The contribution of urbanization, hydroengineering construction and water consumption to runoff changes is assessed. It is shown that the modern 1.6-fold increase in the Moskva River runoff as compared to the period of annual normal flow calculation (3170 × 10⁶ m³) occurred mainly due to anthropogenic factors. The recent runoff increase has been accompanied by a more than two-fold decrease in total wastewater as compared to the end of the 1980s.

莫斯科河流域的现代水文变化

摘要

考虑了在人为和气候因素的影响下，莫斯科河年流量的当前（2015-2017年，可获得必要数据集的时期）变化。将它们与年度正常流量计算的时间段进行比较。与19世纪中叶和1960年代至1980年代（水资源最大的人为负荷时期）相比，还对人为对径流的影响进行了估算。评估了城市化，水力工程建设和水消耗对径流变化的贡献。结果表明，与每年正常流量计算的时期（3170×10 ⁶ m ^3）相比，莫斯科河径流现代增加了1.6倍。）发生的主要原因是人为因素。与1980年代末相比，最近的径流增加伴随着总废水量减少了两倍多。
