The Lena River delta is the largest Arctic delta with an area of about 32,000 km2. It consists of more than 800 branches with a total length of 6,500 km. The Lena delta is underlined by continuous permafrost 500–600 m thick and located in remote and unpopulated area in the Arctic continental climate with the mean annual air temperature by −12.5 °C....

На основе данных стационарного гидрологического мониторинга, спутникового зондирования и расчетов по эмпирическим формулам оценена роль Мамаканского водохранилища в нарушении водного режима и стока наносов рек Мамакан и Витим. Установлено, что трансформация им месячного и сезонного стока очень мала, суточное и недельное регулирование почти не просл...

Geological exploration and mining operations have been conducted in the Vyvenka River basin on the Seinav-Galmoenan platinum deposit since 1994. The majority of the explored and prospective reserves are located in the valleys of spawning salmon tributaries, raising concerns about the environmental impact of mining activities. Despite the cessation...

Lena River is one of the largest “pristine” undammed river systems in the World. In the middle and low (including delta) 1500 km course of the Lena main stem river forms complex anabranching patterns which are affected by continuous permafrost, degradation of the frozen ground and changes in vegetation (taiga and tundra). This study provides a high...

Estimates of the influence of the Vilyuy river reservoir cascade on the transformation of river streamflow discharges and suspended sediments load are presented in the article. The estimates are based on long-term network observations, field measurements in August-September 2021, and satellite imagery. During the fieldwork studies, the horizontal a...

This study presents detailed suspended sediment budget for the four Siberian river deltas, representing contrasting conditions between Northern and Southern environments. Two of the studied rivers empty their water and sediments into the marine located in the permafrost zone in the Arctic region (Lena and Kolyma), and the other two (Selenga and Upp...
