Abstract
The paper provides a statistical analysis of the dynamics of maximum water discharge on the Abakan River and extreme precipitation in the basin of this river in order to identify the main role of the latter in the formation of high and catastrophic floods. The detailed relationships between such floods and extreme precipitation are analyzed using specific examples from 2014 and 2021. Floods in the classes from high to catastrophic mostly occur according to the superimposition of high water on flash floods. The special role of pentad (5-day) maximum precipitation intensity in the occurrence of catastrophic floods has been revealed. Also, a multiple regression model of the dependence of maximum water discharge on three (out of 12) statistically significant climatic predictors, which has quite acceptable reliability and accuracy characteristics, is presented.
