floodplain
Let an agent explain floodplains, their formation and functions, relay flood risk, zoning and restoration information from authorities, identify protected floodplain areas, and distinguish floodplains from related landforms and from other flood-prone areas.
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 floodplains, their formation and functions, relay flood risk, zoning and restoration information from authorities, identify protected floodplain areas, and distinguish floodplains from related landforms and from other flood-prone areas.
The flat land adjacent to a river or stream that is periodically flooded, built from sediment deposited by overbank flows, and forming fertile, ecologically rich and often densely settled areas; floodplains include active floodways and older terraces, are shaped by channel migration and flood regimes, are protected in places as riverine wetlands such as the Traun meadows in Austria, and are managed through zoning, levees and restoration.
What it is for: Not applicable; a landform with ecological and flood management roles.
It can be explain formation and functions; relay flood risk and zoning; relay ecology and restoration; distinguish from related landforms.
Distinguishing features
Overbank deposition
Periodic flooding
Fertile soils
Flood management focus
What it looks like
Flat valley floor beside a river, with meadows, wetlands, oxbow lakes and levees.
How it is recognised
Flat land flooded by an adjacent river
Active floodway and older terraces
Glacier forelands and mudflow areas are different flood-prone landforms; deltas and estuaries are related

What the second pass must settle

- How should flood risk maps be linked?
- The registry entry has merged aliases naming a protected area and unrelated hazards; should they be split off?
