Runoff generation in a low Arctic drainage basin

The production of runoff from a small drainage basin in the continuous permafrost area of continental Canada was studied for two years. The basin comprises two main land types (dry tundra slopes and valley bottom wetlands) and several lakes. In spring, meltwater from most parts of the basin contributed to total runoff but the magnitude and timing of slope and wetland runoff differed. In summer this difference in runoff production was more …
