Permeable Zone (2D)

Permeable Zone (2D) objects are used to link infiltrated volume from the 2D surface into the 1D system. Infiltrated volume in the permeable zone can drain to a selected node, single or multiple links, or a subcatchment in the network. The drainage links for any infiltrated volume can be visually represented on the GeoPlan as arrows.

Permeable Zone (2D) objects can be used, for example, to model the flow through permeable surfaces that are part of a SUDS object which is directed into the drainage system.

Permeable zones can, for example, cover areas with different infiltration properties, and therefore overlap several 2D Infiltration Zones.

Permeable zones intersecting 2D zones are incorporated into 2D zone meshes. The time varying and maxima and minima infiltration results from the 2D engine can be found in the Permeable Zone (2D) Results.

Permeable zones can be imported via the Open Data Import Centre or can be digitised directly on the GeoPlan Window.

Permeable zone parameters are edited in the Permeable Zone (2D) Grid Window of the Polygons Grid or the Permeable Zone (2D) Property Sheet. For further information on creating and editing polygons, see the Digitising Network Objects section.
