Plural of berm; raised barriers or ridges of earth or rock used in construction, mining, or landscaping to prevent erosion or contain materials.
Same origin as 'bermes,' from Dutch/Middle Low German roots, the word evolved to encompass broader meaning in engineering and construction contexts.
Berms are crucial in construction sites and mines—they literally save topsoil and prevent erosion catastrophes, so that innocent-looking dirt ridge is actually environmental engineering!
