| Summary: | Long-term phases of changes of annual and seasonal runoff are analyzed for Lena river basin during period of observation. Main objective of this paper is to analyze the current long-term phase of runoff increase, including an estimation of the contribution of major tributaries of Lena to runoff change at Lena river outlet as well as research of degree of synchronism of observed changes and estimation of possible time of turn to the long-term phase of runoff decrease. Infl uence of the Viljujsky water reservoir on character of long-term changes of annual and seasonal Lena river runoff is estimated too. Анализируются многолетние фазы изменений годового и сезонного стока бассейна реки Лены за период инструментальных наблюдений. В центре внимания – текущая долговременная фаза повышения стока, в том числе оценка вклада основных притоков Лены в изменение стока в замыкающем ее створе, а также исследование степени синхронности наблюдавшихся изменений и обоснование временной границы смены направленности фаз. Оценивается также влияние Вилюйского водохранилища на характер долговременных изменений стока Лены. |
