Presented is the method to assess the duration and character of floodplain inundation during a flood (exemplified by the floodplain of the Middle Ob in the area of the city of Kolpashevo). It is based on analyzing data from the Kolpashevo gauging station, and on the floodplain terrain model. The floodplain inundation duration was estimated from inundation duration curves. By constructing the relief of the floodplain, it was possible to assess the character of water input and runoff from the floodplain, and the influence of the floodplain flow on the river channel.
