Spatial Rain Source Data Fields (SWMM)

Spatial rain source data can be edited on either the Spatial Rain Source Grid Window of the Polygons Grid or the Spatial Rain Source Property Sheet.

The following describes all the data which can be used to define a Spatial Rain Source.

Common Data Fields

Fields that are common to the majority of objects can be found in the Common Fields topic.

Spatial Rain Source Data

Field Name	Help Text	Database Field	Data Type	Size	Default	Error Lower Limit
ID	Unique identifier for the spatial rain zone.	id	Text	254
Source type	Type of source. Available sources are: Rain gage polygons - TVD connector polygons of type rainfall Spatial TSDB observed - Spatial Times Series Database of data type observed Spatial TSDB forecast - Spatial Times Series Database of data type forecast	source_type	Text	32	Rain gage polygons
Stream or category	For spatial time series database source types, this is the name of the stream within the TSDB. For rain gage polygons, this is a category name (which may be blank). The source comprises all the rainfall TVD connectors that have that name in their category field. The latter allows users to divide the rain gages into multiple groups (e.g. if some are polled more frequently or are more reliable than others).	stream_or_category	Text	254
Priority	Source priority. Note The priority set here overrides the settings entered in the SWMM Schedule Hydraulic Run View. Defines the order in which InfoWorks ICM applies the rainfall sources for the time window specified in the Start hours relative to origin and/or the End hours relative to origin fields.	priority	Long Integer			0
Start seconds relative to origin	The number of seconds, relative to the forecast origin time, at which to start using the source. If blank, the start of the simulation will be used. Negative values are before the forecast origin, positive values are after. Note The value set here will still be applied when using Historic mode on the TSDB Options Dialog. Configuration of time windows for Spatial Rain Sources is not recommended when using Historic mode.	start_time	Double
End seconds relative to origin	The number of seconds, relative to the forecast origin time, at which to stop using the source. If blank, the end of the simulation will be used. Negative values are before the forecast origin, positive values are after. Note The value set here will still be applied when using Historic mode on the TSDB Options Dialog. Configuration of time windows for Spatial Rain Sources is not recommended when using Historic mode.	end_time	Double
