On Ice Jam Formation in the Middle Lena
Abstract Ice jams are an integral part of the ice regime of the rivers of the Lena basin, and reach the greatest scales here [1]. Huge masses of ice moving downstream form hummock accumulations, clog the river bed and form ice dams. The nature of ice jams is determined by the conditions of flood for...
