drainage divide
Let an agent explain drainage divides and their kinds, relay hydrological principles and examples from geography sources, describe continental and triple divides, and distinguish the divide from the drainage basin, from watershed in its two senses and from political boundaries that follow divides.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain drainage divides and their kinds, relay hydrological principles and examples from geography sources, describe continental and triple divides, and distinguish the divide from the drainage basin, from watershed in its two senses and from political boundaries that follow divides.
The line of high ground separating adjacent drainage basins so that precipitation on each side flows to different rivers or seas, from continental divides such as the Great Divide of the Americas and the main watersheds of Europe including those in Germany through triple divides where three basins meet to minor divides on valley floors; drainage divides define watersheds and are used in hydrology, mapping and boundary making.
What it is for: Delimiting drainage basins.
It can be explain the concept and kinds; relay principles and examples; describe continental divides; distinguish related terms.

Boundary use
What it looks like
A ridge or high ground line on a map.
Physical character
Great Divide of the Americas: from Alaska to Tierra del Fuego note
Triple Divide Peak, Montana: Pacific, Atlantic, Hudson Bay note
European main watershed: Atlantic versus Mediterranean and Black Sea note
How it is recognised
High ground separating drainage basins
Continental divide, main and central watersheds, triple divide, valley floor divide, watersheds in Germany
The basin is the area drained; watershed means divide in British and basin in American usage; borders may follow divides

What the second pass must settle
- Should continental divide and triple divide be separate primary entries?
- How should geography sources be linked?
- The registry entry has merged aliases naming kinds and German watersheds; should they be split off?
