IStormwaterLID Interface

Interface for a stormwater Low-Impact-Development structure.

A stormwater LID is a small scale hydrologic structure, that can store, detain, infiltrate (and/or similar) water close to where the water origin from.

The stormwater LID is attached to a catchment. It can overtake some of the catchment area (TotalCollectingArea and Area).

public interface IStormwaterLID

The IStormwaterLID type exposes the following members.

Properties
  NameDescription
Public propertyArea
Area of LID.

This is the area used for rain and evaporation, i.e. if set to 0.5 times the catchment area, then half of the rain falls on the catchment and half of the rain on the LIDs directly.

The sum of all Area for all LIDs within a single catchment must be less than the area of the catchment they belong to.

For some LIDs (e.g. rain barrel), this area is zero.

Public propertyFlowStat
Flow statistics and mass balance
Public propertyFractionOfLIDFlowToRoute
Fraction of runoff flow from the LIDs that are routed by the catchment. The remainder will be added directly to the catchment runoff (not routed).

The different catchment types may treat this differently.

Default value: 1. Unit: [fraction]

Public propertyName
Name of the LID
Public propertyRunoff
Runoff from LID at the current time step
Public propertyTotalCollectingArea
Total collecting area is the area from which water is routed through the LIDS, either because rain is falling directly on the LIDs (Area) or when catchment rain (after losses) is routed to the LIDs.

This area is used by the catchment to figure out how much water should be routed to the LIDs, effectively splitting the catchment area in 3 parts:

Copy
catchment-No-LID-Area       = ICatchment.Area - sum(IStormwaterLID.TotalCollectingArea)
catchment-Route-To-LID-Area = sum(IStormwaterLID.TotalCollectingArea - IStormwaterLID.Area)
LID-area                    = sum(IStormwaterLID.Area)
The sum of all 3 contributions is the area of the catchment.

The TotalCollectingArea cannot be smaller than Area.

The sum of all TotalCollectingArea for all LIDs within a single catchment must be less than the area of the catchment they belong to.
