LID in Rainfall Runoff models

Classes

BioRetentionCell Bio-retention Cells are depressions that comprise vegetation grown in an engineered soil mixture sited above a gravel drainage bed. They offer storage, infiltration and evaporation of both direct rainfall and runoff captured from surrounding areas. Rain gardens, street planters, and green roofs are all different types of bio-retention cells.

if disabling the storage by setting Storage.Height to zero, this effectively models the Rain Garden LID type. The infiltration to outer soil is in this case the percolation, Perc.

CatchmentSurfaceLegacyLIDs Catchment surface handling Low-Impact-Development structures.
CatchmentSurfaceLID Catchment surface handling Low-Impact-Development structures.
CatchmentSurfaceLIDCreator Class for creating surfaces with LIDs
GreenRoof Green Roofs offers filtering, absorbing, delaying rainfall.

They are built of a lightweight soil media, a drainage layer, a coverage planted surface which can allow minimum additional storage.

InfiltrationTrench Infiltration Trenches are narrow waterways filled with gravel that capture runoff from upslope impervious areas. They offer storage capacity and additional time for captured runoff to infiltrate the inherent soil underneath.
LIDBase Base class for LID classes, holding common parameters and functionality.
LIDBaseOffers LID base class containing functionality to deal with offers
LIDConnection Connection between LIDs
LIDConnectionData Class specifying what area of catchment surface does the LID take.
LIDExtension Extension class for LID related methods
LIDFlowStat Class handling flow-statistics of LID
LIDLayerDrainMat Drain mat LID layer
LIDLayerPavement Pavement LID layer
LIDLayerSoil Soil LID layer
LIDLayerStorage Storage LID layer
LIDLayerSurface Surface LID layer.

To enable surface routing, both the ManningM and the Slope must be set.

LIDResultFileWriter Class for writing LID results to file (dfs0)
PorousPavement Porous Pavement systems are excavated areas filled with gravel and paved over with a porous concrete or asphalt mix. Normally all rainfall will immediately pass through the pavement into the gravel storage layer below it where it can infiltrate at natural rates into the site´s native soil.
RainBarrel Rain Barrels are containers that collect roof runoff during storm events and can either release or re-use the rain water during dry periods.

StormwaterLIDs Class handling total flows from LIDs.
SurfaceAreaForLID Class specifying what area of catchment surface does the LID take.
VegetativeSwale Vegetative Swales are waterways or depressed areas with sloping sides covered with grass and other vegetation. They slow down the conveyance of collected runoff and allow it more time to infiltrate to inherent soil beneath it.
