Abstract: The computer hydraulic model of formation of an ice jam levels on the rivers is considered in the reporting. The model is based on construction of a digital model of a relief with application of GIS-technologies and numerical solution of the equations of the Saint-Venant in a one-dimensional and two-dimensional schematization. The accounts of a disastrous jam of 2001 in region of city Lensk in Ykut region are conducted. The good concurrence to full-scale dates was obtained. A main outcome that by primary factors, defining an ice jam levels, are length of a jam and water discharge. Height of an ice dam in the basis of a jam is not the main reason of rise of a level of water. It allows to evaluate recurrence of a jam levels.
