[′pär·shəl ′ped·ə·mənt]
(geology)
A broadly planate, gravel-capped, interstream bench or terrace.
A broad, planate erosion surface which is formed by the coalescence of contemporaneous, valley-restricted benches developed at the same elevation in proximate valleys, and which would produce a pediment if uninterrupted planation were to continue at this level.
