Models of Slope Development: Davis, Penck, King, Wood and Strahler

The evolution of slope is concerned with the change of slope forms with the passage of time. Models of slope evolution investigate the processes and mechanisms that operate to produce a particular slope form. The second half of the nineteenth century saw some noteworthy work in this direction.

The following are the models of slope development:

The term ‘Slope Decline’ is used by Davis to indicate the process of slope evolution where the steepest part of the slope declines with the development of convexity and concavity.

Penck, on the other hand, emphasized ‘Slope Replacement’, where the maximum angle declines due to its replacement by gentler slopes from below, causing a greater part of the slope profile to become concave.

L. C. King discussed ‘Parallel Retreat’, where the maximum angle remains constant, but the concavity gradually increases in length.

Wood defined elements of slope and discussed the development of hillside slopes.

Strahler used statistical techniques in his work and analysed factors affecting slope evolution.
