A link represents the physical connection between two nodes and may be one of the following:

In the InfoWorks ICM network, each node must be connected by a link to at least one other node. A single node may have several links to other nodes.

A conduit that changes direction can be represented by two links, with a node at their junction.

For each link, one of the nodes must be specified as the 'upstream' end. This identifies the nominal direction of flow but is not necessarily the direction in which the water will always flow.

The upstream node – in combination with the invert level at the upstream end – is used by the system for allocating a unique label to the link.

The link's downstream node is given for information.

In the same way as for nodes, new links can be added to the network using either the GeoPlan Window or the Links Grid Window.
