Protection of the Urbanized Area of Bishkek City from Ice Jams in Small Rivers of Kyrgyzstan

The article presents the results of a comprehensive study of ice jam formation processes in small rivers, in the example of the Ala-Archa River, flowing through the territory of Bishkek. The relevance of the work is due to the stable recurrence of ice jams (2.3 ± 0.4 cases/year), causing flooding of urban infrastructure. Visual observations of the duration of ice jams in the studied rivers were conducted, with GPS data collected at observation points along the banks. The hydrological, hydraulic, and morphological conditions of the riverbed were also examined. This study of ice jamming processes found an engineering solution to the problem of protection from the formation of ice jams in dangerous areas.
