A link is defined as a connection between two nodes. Links cannot exist without nodes at the end points, and the direction is indicated by the arrow line.

When the link tool is selected, the cursor changes to a link shape, and the application will allow you to create connections between nodes. The first click on the window defines the node from which the link emanates. The next and subsequent mouse clicks identify the node to which the link joins. A straight line is then drawn between these two nodes with an arrow indicating direction.

River Link.  This tool draws a segmented River Reach comprised of river segments and intermediate river nodes, and is the default object when importing HEC RAS models. This specialized link contains the open channel cross section and limits the input for the typical river reach. It is designed to simplify the modeling process for users with river modeling experience.

Conduit data is shared amongst all three modes: Runoff, Sanitary, and Hydraulics. Each layer (module) routes flow differently, increasing in complexity in the order above. The Sanitary layer uses a Kinematic Wave approach for conduit routing, in which disturbances are allowed to propagate only in the downstream direction. As a consequence, backwater effects are not modeled beyond the realm of a single conduit, and downstream conditions (eg. tide gates, diversion structures) do not affect upstream computations.
