Description
Erosion and sedimentation caused by glacial ice results in overdeepening of valleys, scouring of upland areas, deposition of glacial moraines and modification of stream channel networks. The net effect is similar to that of fluvial erosion/sedimentation - potential shortening of flowpaths and modifications of the biosphere. During the course of the next million years, glacial erosion in northern Switzerland could lead to further deepening of existing valleys/channels.
