Archeologists use the term to define narrow spaces such as those between banks and ditches . It can also be used to describe a linear bank raised to separate two areas. In Mediaeval Military Engineer ing a berm or '''berme''' was a level space between a Parapet or Defensive Wall and an adjacent steep-walled Ditch or Moat . It was intended to reduce Soil Pressure on the walls of the excavated part, to prevent it collapsing. In the Trench Warfare of World War I , the name was applied to a similar feature at the lip of a Trench which served mainly as an elbow-rest for a Rifleman while firing. In Noise Pollution , berm is a Noise Barrier constructed of earth, often landscaped, aligned along a highway to protect adjacent land users from excessive intruding noise. In Natural Building , berming refers to piling earth against an exterior wall to create thermal mass or reduce the visible footprint of an Earth-sheltered Home . In modern military engineering, berm has come to refer to the wall or parapet itself, when it is constructed of earth or Sod . The term especially refers to a low earthern wall adjacent to a ditch which provided the spoil from which the wall was constructed, typically constructed in a continuous action by a Bulldozer or Combat Engineering Vehicle . Walls constructed in this manner are an effective obstacle to vehicles, including most Armoured Fighting Vehicle s, but are easily crossed by Infantry . Because of the efficiency of construction, such walls can be made hundreds or thousands of kilometres long. SEE ALSO In North Dakota, a Berm refers to the strip of grass-lawn that is located between the sidewalk and the street-curb. |
