HYDRODYNAMIC CONDITIONS OF FORMATION AND ARTIFICIAL DESTRUCTION OF ICE JAMS ON THE LENA RIVER

V. V. Kilmyaninov

The Lena River near the towns of Lensk and Yakutsk is chosen for a case study of the role of discharges and flow velocities in the formation of ice jams in narrow and broad river channels. Hydrodynamic conditions that prevent or ease artificial destruction of ice jams are discussed.
