In the Upper Ob river basin, emergency events (EE) are mainly associated with flooding and underflooding of settlements and economic facilities. Using the landscape-basin approach and geoinformation-cartographic method, we analyzed different monitoring data on flooding and flooding zones within the boundaries of five regions (the Republic of Altai, Altai Krai, Kemerovo, Novosibirsk and Tomsk oblasts) for the 25-year period. Spatial-temporal variability of data series was studied and most flood-prone river basins as well as physical and geographical zoning units were defined. A comparative analysis of two periods (1993-2002 and 2004-2018) was performed, trends in emergency occurrence were revealed, and the findings were presented in a cartographic format. The established general patterns of emergency manifestation can be used to identify the causes of occurring processes. In the future, it will allow to forecast emergency events and minimize probable damage to population and economy.
