WebSep 1, 1992 · He based his interpretations of landforms and landscapes firmly in the concept of parallel scarp retreat, for although he acknowledged the possibility of slope decline in certain lithological and vegetational environments, he used the mechanism little, if at all, in understanding landscape. WebSteeper gradient facilitates more active retreat than gentle gradient. The slope retreat occurs in parallel manner which results in the replacement of lower segment of slope profile by new unit of gentle gradient. Flattening of slopes always takes place from below upward.

WebParallel Retreat The climate, rock type, and rock structures are the most important factors in slope erosion. As previously noted, rocks of different compositions weather at different rates—harder rocks form steeper slopes and generate coarser‐grained, more angular talus slopes that are resistant to weathering and erosion.

http://www.mbbcollege.in/db/notes/511.pptx WebParallel retreat A slope maintains a constant angle as erosional retreat of the ground surface cuts back into the bed rock found in arid environments. Slope decline Occurs as steep slopes gradually become shallower, flattening the overall slope profile. Then end result is a profile with a convex upper slope and a concave lower slope.

Parallel slope and scarp retreat, albeit proposed by early geomorphologists, was notably championed by Lester Charles King. King considered scarp retreat and the coalescence of pediments into pediplains a dominant processes across the globe.
