SWMM - LID Controls - Vegetative Swale

Vegetative Swale - are channels or depressed areas with sloping sides covered with grass and other vegetation. They slow down the transport of the collected runoff and allow it more time to infiltrate the native soil below it.

Schematically:

• SWMM
  • Surface (LidSurface, SwmmLidDataSurface)
    • Vegetable Coverage (VegetalCover, Double) - Vegetal Coverage
    • Slope (SurfaceSlope, Double) - Surface slope
    • Side Slope (SwaleSlope, Double) - Slope of the side walls of a cross section of a ditch
    • Storage Depth (BermHeight, Double) - Storage Depth
    • Surface Roughness (SurfaceRoughness, Double) - Roughness
