FACTORS AND TRENDS OF THE LONG-TERM FLUCTUATIONS OF WATER, SEDIMENT AND HEAT RUNOFF IN THE LOWER REACHES OF THE LENA RIVER AND THE VILYUI RIVER
Abstract
Specific features and trends of seasonal and long-term fluctuations of water, suspended sediment and heat runoff in the lower reaches of the Lena River and the Vilyui River are discussed. New estimates of runoff distribution parameters are presented. Both climatic and anthropogenic factors of the spatial and temporal variability of river runoff parameters and water temperature are analyzed, as well as the contribution of the processes characteristic of the upper and lower reaches of the Lena River, the Aldan and Vilyui rivers basins, to these changes. The contribution of different factors to the variability of a number of main hydrological parameters was quantified. The influence of reservoirs on some river runoff parameters and temperature characteristics of the Vilyui River is considered. A number of computational and prognostic empirical relationships are presented.
