meander
Let an agent explain meanders and how they form, relay geomorphology, measurement and examples from river science sources, describe cut-offs and oxbow lakes, and distinguish meanders from braided channels, from the decorative meander pattern and from the meander in other senses.
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 meanders and how they form, relay geomorphology, measurement and examples from river science sources, describe cut-offs and oxbow lakes, and distinguish meanders from braided channels, from the decorative meander pattern and from the meander in other senses.
A pronounced bend in a river or stream, formed as flowing water erodes the outer bank and deposits sediment on the inner bank, so that the channel migrates across its floodplain in a series of loops, sometimes cut off to leave oxbow lakes; the term comes from the winding Maeander river in Anatolia, and the registry treats the meander as a water area, the river bend itself.
What it is for: Not applicable; a river feature.
It can be explain formation; relay geomorphology; describe related features; distinguish related concepts.
Distinguishing features
Outer bank erosion
Inner bank deposition
Lateral migration
Cut-offs and oxbows
What it looks like
A looping bend of a river seen from above.
Physical character
meander wavelength: about 10-14 times channel width note - empirical
sinuosity threshold: above about 1.5 note - for meandering
name origin: Maeander river, Anatolia note
How it is recognised
Pronounced river bend
River bend, meander loop, oxbow lake after cut-off
Braided channels split around bars; the decorative meander is a key pattern; other senses are figurative

- How should the registry separate the decorative pattern sense?
