Pediplain

In geology and geomorphology a pediplain (from the Latin pes, genitive case pedis, meaning "foot") is an extensive plain formed by the coalescence of pediments.

[2] The concepts of pediplain and pediplanation were first developed by geologist Lester Charles King in his 1942 book South African Scenery.

[3][A] The coalesced pediments of the pediplains may form a series of very gentle concave slopes.

[B] Pediplains main difference to W. M. Davis’ peneplains is in the history and processes behind, and less so in the final shape.

[1][3] In contrast to common peneplain conceptualizations several pediplains might form simultaneously at different altitudes and do not necessarily grade to a base level.
