Runoff Regime of Slopes in Continuous Permafrost Areas

The hydrological regime of slopes underlain by continuous permafrost is dictated by the seasonal differences in the supplies of water and energy. Based on a study at Resolute, N.W.T., three hydrological seasons are recognized. In winter, the ground freezes, snow accumulates, and most hydrological activities on the slopes are dormant. As energy supply increases in spring, snowmelt generates considerable runoff but frozen ground restricts …
