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.

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.
