About Nodes
Nodes represent places where actions or measurements occur in a river system, where water can be added, extracted, stored, recorded, or change ownership in a model. A node can be used to represent things that actually happen over a large physical area but that, for modelling purposes, occur at a single point. In sub-catchments, they provide a position in the catchment network where water management information can be placed. In Source, nodes are depicted using the icons shown in Figure 1.

Note: Source does not support duplicate names for nodes or links and will warn you if there is one. You must ensure that the names you choose are unique to the scenario (schematic). |
Editing nodes
Use the feature editor of a node to change the parameters associated with them. To open a feature editor you can either double click on the node icon, or right click on the icon and select Edit.
Searching for nodes and links
...
Deleting nodes can be achieved simply by selecting the node and pressing the delete key, or by right-clicking it and choosing Delete from the contextual menu. Deleting a link removes only the link. Deleting a node removes both the node and any links that were attached to the node.

Adding notes to nodes and links
You can include add a text-based message associated with a node or link, which can be either:
...
or
...
Each of the different message types has a different icon. Figure 5 shows an example of an informational note added at an Inflow node.

A summary of all nodes can also be viewed using View » Notes (shown in Figure 6). This provides a summary of all the notes in the scenario, along with the node or link it is associated with.
