Currently, dynamic processes, affecting runoff in catchments, are poorly understood. Among all the elements of water balance calculations, the streamflow is the most accurately measured and largely reflects the current moisture content of the active layer. Devices for automatic measurement of water level and temperature of soil, water and air were installed in four small catchments with different climatic conditions. The studied catchments are located in a zone of oligotrophic swamps of the southern taiga, a zone of hilly swamps of the forest-tundra, a foothill zone of the southern taiga, and a mountain-glacial basin. Runoff in the mountain-glacier basin is determined using an acoustic level meter of the water flow. As a result: Site 1) We have revealed a change in the water-physical properties of the active layer in the marshy catchment, which resulted from the 2012 drought; Site 2) We have shown the linkages of the moisture content of the soil above the water table with extreme water discharge in active watersheds; Site 3) The increase in autumn runoff is due to thawing of seasonal permafrost and snow-melt in the tundra; Site 4) In the mountain-glacier basin, our studies are at an initial stage.
