LIDBaseTotalCollectingArea Property

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: 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.
