Его оценка проводится на основе данных о стоке и мутности воды, доступных по ограниченному числу гидрометрических постов. В статье проведено обобщение информации с 53 гидрометрических постов (с продолжительностью измерений не менее 8 лет) в бассейне Лены. Выполнена оценка факторов формирования мутности для их водосборов (характеристики потери почвы, морфометрии рельефа, стока воды, антропогенной нарушенности русел). На этой основе получены регрессионные зависимости формирования мутности, пересчет которых на 700 водосборов средних рек бассейна позволил воспроизвести пространственное распределение мутности воды в пределах бассейна Лены за два отрезка времени, соответствующих всему периоду инструментальных наблюдений и современному климатическому периоду (после 1978 г.). Распределение мутности воды наглядно отражает контрастный режим эрозионно-аккумулятивных процессов в речном бассейне. Области эрозии с 2–3-кратным усилением денудации в последние десятилетия приурочены к горным районам, располагающимся по периферии водосбора. Средняя мутность воды в бассейне достигает максимальных значений &gt;50 г/м3 на притоках Витима (Муя, Таксима, Бамбуйка, Мама), где ведется разработка полезных ископаемых, на притоках Олекмы-Чара и Дырын-Юрях, в восточной и южной частях бассейна Алдана. Полученные данные являются основой в дальнейших балансовых оценках перераспределения вещества в речном бассейне и могут быть использованы для определения стока наносов на неизученных участках речной сети.</p></abstract><kwd-group xml:lang="ru"><kwd>сток наносов</kwd><kwd>водосбор</kwd><kwd>морфометрия</kwd><kwd>эрозия</kwd><kwd>климат</kwd><kwd>р.
