Abstract
The purpose of the study is to study the intra-annual distribution of water levels, taking into account ice conditions. An assessment of the recurrence of ice phenomena at hydrological stations with a high frequency of exceeding the level of a dangerous hydrological phenomenon (DHP) and an unfavorable hydrological phenomenon (UHP) was carried out. The values of the value of the excess of the highest water level over the established critical water levels of the DHP or UHP have been calculated. It has been revealed that on the territory of the studied region, the excess of the marked and DHP occurs not only during spring floods, ice jams, but also ice movements, autumn and spring ice drift, and even under non-compact freezing. Underestimation of the level and ice regime significantly complicates the implementation of measures to prevent and minimize the negative consequences and damage from dangerous ice hydrological phenomena.
