Description
A hydrographic node corresponds to a change in the flow of water. It is always located at the end of a basic hydrographic section.
The class of hydrographic nodes managed by the IGN includes:
- confluences, diffluences, sources, mouths and losses of watercourses;
- restraint dams;
- run-of-river dams;
- locks (for passage or refit);
- springs and waterfalls of tourist interest.
A hydrographic node is located by a geometric vertex. Some nodes correspond to an outlet of a hydrographic zone.
