Infiltration Zone (2D) Data Fields

Infiltration Zone (2D) data can be edited on either the Infiltration Zone (2D) Grid Window of the Polygons Grid or the Infiltration Zone (2D) Property Sheet.

Most data can be edited on the grid, but some fields cannot be displayed in the grid format.

To view and edit all zone data, use the Property Sheet.

The following describes all the data which can be used to define an Infiltration Zone (2D).

Common Data Fields

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

Infiltration Zone (2D) Data

Database Table Name: hw_2d_infiltration_zone

Show Columns	Database Names
	Size, Type and Units
	Defaults and Error Limits

Field Name	Help Text	Database Field	Data Type	Size	Units	Precision	Default	Error Lower Limit	Error Upper Limit
ID	The name of the zone	polygon_id	Text	64		0
Area	Zone area. Default value calculated from polygon geometry.	area	Double		CA	3
Infiltration surface	The name of the Infiltration Surface (2D) applied to this zone.	infiltration_surface_id	Text	64		0	DEFAULT
Rainfall percentage	Percentage indicating how much of the rainfall depth will fall directly onto the ground within the Infiltration zone. Used to avoid double counting, e.g. of rainfall falling onto building roofs and flowing directly into the drainage system.	rainfall_percentage	Double			3	100	0	100
Exclude infiltration zone boundary when creating 2D mesh	Determines whether the boundary of the zone is enforced as a break line when Creating 2D Meshes: Checked: Do not enforce zone boundary as a break line. Infiltration zone parameters will be assigned to 2D mesh elements for which the centroid falls within the infiltration zone. Unchecked: Enforce zone boundary as a break line. The infiltration zone parameters will be assigned to all 2D mesh elements within the infiltration zone.	exclude_from_2d_mesh	Boolean			0	1
Boundary Array	An array of X/Y values defining the geometry of the zone.	boundary_array	Array		XY	0
