What is a berm in landscape management?

A berm in landscape management is indeed defined as a raised bench or terrace situated between two slopes. It typically serves several functions in erosion control and stormwater management. A berm can help to reduce runoff speed, provide a barrier to direct water flow, and facilitate sediment deposition. By elevating the terrain, it can also assist in channeling water flow in a more controlled manner, which helps to minimize erosion risks in surrounding areas. This characteristic makes berms valuable in both agricultural settings and urban landscape designs where managing water flow is crucial for soil preservation and environmental protection. Understanding the role of berms helps in effective landscape planning and the implementation of erosion and sediment control measures.
