Terrace Technical Terms
Terrace: A step-like surface, bordering a valley floor or shoreline, that represents the former position of a flood plain, or lake or sea shore. The term is usually applied to both the relatively flat summit surface (tread), cut or built by stream or wave action, and the steeper descending slope (scarp, riser), graded to a lower base level of erosion. Compare - stream terrace, flood-plain step. HP. [ soil survey] Practically, terraces are considered to be generally flat alluvial areas above the 100 yr. flood stage. SW
