Berms are effective for treating smaller, flatter drainage areas. Berms can be used on larger sites by installing multiple berms to partition the drainage area so that individual structures are not overwhelmed by incoming flow. Berm effectiveness is reduced when slopes exceed 10 percent. See more Berms prevent off-site sedimentation by diverting runoff to a sediment trapping device and can also be used to divert clean water from entering a disturbed area. They can also … See more The size, soil condition, and topography of the site must be considered before selecting, sizing, and installing a stabilized berm.

Contrarily to impermeable berms above SWL, a permeable berm above SWL leads to significant reduction of overtopping. The measured spatial distribution of overtopping is associated with a lot of seemingly random behaviour.
WebThe effect of a permeable berm on total overtopping was found to be remarkably different from the effect of an impermeable berm. Permeable berms below Still Water Level (SWL) lead to less reduction of overtopping than impermeable berms below SWL. Berms above SWL lead to wave breaking on the slope in front of the berm.
