K. I. Kusatov, A. P. Ammosov, Z. G. Kornilova, and R. N. Shpakova

The analysis of ice jam formation processes of anthropogenic nature in the middle reach of the Lena River in 2001 and 2010 is carried out. Peculiarities of ice jam formation, springflood and inundation of villages in the Republic of Sakha (Yakut Republic) related to preventive actions are demonstrated. Intensity of variation of stages of spring ice jam flooding at the Lena River streamgage sites is considered. The degree of anthropogenic factor effect on ice jams through hydrological and hydromorphological processes is demonstrated.
