BERM - A horizontal step or bench in the upstream or downstream face of an embankment dam.
(1) On a beach: a nearly horizontal plateau on the beach face or backshore, formed by the deposition of beach material by wave action or by means of a mechanical plant as part of a beach renourishment scheme. Some natural beaches have no berm, others have several. (2) On a structure: a nearly horizontal area, often built to support or key-in an armor layer.
A horizontal strip or shelf built into an embankment or cut to break the continuity of the slope, usually for the purpose of reducing erosion or to increase the thickness of the embankment at a point of change in a slope or defined water surface elevation. A horizontal step in the sloping profile of an embankment dam. A shelf that breaks the continuity of a slope, or artificial ridge of earth. A ledge or shoulder, as along the edge of a road or canal. An artificial ridge of earth.
The nearly horizontal portion of a beach or backshore having an abrupt fall and either formed by deposition of material by wave action at the limit of ordinary high tide or constructed to protect materials handling equipment during air cushion vehicle operations.
1. A berm is a mound of earth, generally of triangular (or trapezoidal) cross-section, that parallels a roadway and serves as a noise barrier.
2. A berm is the area between back slope and the right of way (ROW) line.
3. A berm is a ledge or shelf that breaks the continuity of a slope.
Berm has been defined 18 different ways in documents like Dam Safety, Unified Development Ordinance, Chapter 13, Glossary of Coastal Terminology, and 7 more.
