Abstract

Studies of contemporary patterns of erosion in the glaciated and largely undisturbed Canadian landscape reveal spatial patterns that do not conform to the conventional concepts of drainage basin sediment delivery. In particular stream and valley side sediment sources dominate over erosion of the land surface, and specific (unit) sediment yield is often positively, rather than inversely, related to drainage area. Only in the agricultural areas of the Great Lakes basin and St. Lawrence valley do more conventional patterns of erosion occur. Applied studies related to agricultural soil erosion and pollution have helped to illuminate the pathways and sources of sediment in particular cases and show the effects of landscape disturbance
