Berms can be used to direct flow of water through permanent ponds, ephemeral pools and [[constructed wetlands]], or on slopes with [[vegetated filter strips]].  
 
They may be utilised to divert water through the wetland, creating a longer flow path. This increases the efficiency of the system by increasing the hydraulic residence time. The top of the banks may be below or above water level. Flow diversion banks are usually submerged at nominal operating level.
