slope profile


Show Summary Details

Quick Reference

The two-dimensional form of a hill-slope when measured down the steepest gradient, traditionally divided into a number of units, each reflecting a distinctive geomorphological process. For example, in 1957 L. C. King identified four elements in his ideal profile: a crest (or ‘waxing slope’ or ‘convex slope’) dominated by creep; a scarp (or ‘free face’) affected by rill activity and mass movement; a debris (or ‘constant’) slope where talus accumulated; and a pediment (or ‘waning slope’) modified by sheet-wash. Subsequently, a nine-unit model has gained some acceptance.
