A methodology for assessing the prevalence of raised, transitional and lowland swamps has been developed and tested (using the example of a number of river catchments in the Ob River basin within the boundaries of the Tomsk region). This methodology is based on taking into account materials from water and peat cadastres, and remote sensing data. It can be used in the study of hydrologically unstudied or insufficiently studied rivers in the taiga zone of Western Siberia for assessing the parameters necessary for selecting analogue rivers, calculations of maximum and minimum water flow, determining the boundaries of swamps and flood zones. Using the tributaries of the Middle Ob as an example, the scale of swampiness was clarified. Taking these data into account, it is shown that, firstly, there are favorable conditions for the accumulation of organic substances and substances associated with their transformation in the territory under consideration. Secondly, economic activity in the taiga zone currently in a number of cases contributes to waterlogging and, accordingly, further swamping of the territory.
