Network Objects

In InfoWorks ICM, a network is a representation of a drainage system, usually displayed over the top of a scale map of the drainage area.

Network objects are divided into categories as described below.

Nodes

A node represents a physical structure in the drainage system.

Links

A link represents the physical connection between two nodes.

The main types of link available are:

Subcatchments

Subcatchments represents the physical area from which a manhole or other inflow node collects water.

Polygon Objects

Polygon Objects provide a method for specifying a geographical area on the GeoPlan Window.

Network Results Polygon (2D) objects are used to interrogate results within a 2D mesh (InfoWorks networks only).

Lines

Lines are used:

  • To geographically represent features such as walls and sections
  • In the process of building a River Reach, a Bridge or an Inline Bank object (InfoWorks networks only)
  • In the 2D meshing process

Network Results Line (2D) objects in InfoWorks are used to interrogate results within a 2D mesh.

Points

The Point objects in an InfoWorks network are:

In SWMM networks, the only Point object is a Rain Gage, which is associated with a rainfall profile from a rainfall event to provide a source of precipitation data for use in subcatchments or unit hydrograph groups.

You can easily navigate from an object to many adjacent or associated objects using options on the Property Sheets and Grid Windows.
