Аннотация доклада:
The study introduce the application of various empirical and conceptual erosion models for the large river basin (more than 2 500 000 km2) in the east part of Russia (Lena river). The RUSLE and USPED models were used to predict sediment concentrations and yields in the river of Lena basin. By using sediment delivery ratio all mean annual soil losses modeled in GIS were recalculated into sediment yield (t/km2). Further calculations allow to estimate percentage of sediments from rill and interill erosion in total sediment export.
