FLOOD ICING IN SMALL RIVER VALLEYS OF THE CENTRAL PART OF SELENGA HIGHLANDS: THE DYNAMICS AND CURRENT STATE

The article presents data on the spatiotemporal dynamics and current state of flood icing formed in the small catchment basins of permanent streams (small rivers and streams) with sources in the spurs of the Tsagan-Daban Ridge. It has been found that during the win- ter period there are up to 250 small icings formed within the studied territory (5700 km2), their total area can reach 11 km2. The dependence of the morphometry of ice fields on the climatic factors of the environment is reflected in the long-term dynamics of the studied icings, which belong to the very small and small ones. We have performed mapping of flood icing. The obtained results can be used in forecasting the growth and development of icing that threaten the safety of settlements.
