Solifluction and related processes, eastern Banks Island, N.W.T.
Mean surface soil movement measured over the period 1972–1983 on eight relatively low angle (< 10°), well drained slopes on eastern Banks Island averaged 0.6 cm/year. Substantial variation in mean movement was recorded amongst the slopes. The variation relates to differences in soil moisture cond...
