The flattened portion of an earth fill is called a berm. In the context of earthworks and embankment construction, the berm serves as a flat or slightly inclined area that is typically located at the top or sides of an embankment. This feature provides several functions, including enhancing the stability of the fill by preventing erosion and allowing for proper drainage.

Berms are essential in roadway and structural design, as they help to support the embankment while providing a space for maintenance or temporary storage of materials. They also serve to mitigate the effects of slope runoff and can be beneficial for visual aesthetics. Understanding the role and characteristics of a berm is vital for anyone involved in the design and construction of earth structures as it directly influences the performance and safety of the conducted works.
