|Best Management Practice Fact Sheet 2: Sheet Flow to Open Space
Sheet flow to open space (SOS) is a group of best management practices (BMPs) designed to disperse concentrated runoff to sheet flow into filter strips or a riparian buffer. An SOS reduces runoff volume and associated sediment and nutrients that are carried with it (see figure 1). It is used as a stormwater treatment practice in both urban and rural areas. This practice is often used after another treatment practice to disperse or eliminate runoff. In a few cases, an SOS can be used as a pretreatment to remove small amounts of sediment via a vegetated filter strip — prior to a bioretention device, for example.
