watercourse
Let an agent handle watercourses by type, flow, ownership, regulation, flood risk and ecology.
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 handle watercourses by type, flow, ownership, regulation, flood risk and ecology.
A channel through which water flows, natural or artificial, such as rivers, streams, brooks, canals and ditches, and associated structures such as spillways, culverts and sluices.
What it is for: Carrying water, drainage, navigation, habitats and flood control.
It can be map and name watercourses; check permits for works near water; monitor flow and quality; manage flood risk.
Distinguishing features
Channel with flowing water
Natural or artificial
Regulated for works and pollution
Linked to flood risk
What it looks like
Channels of flowing water with banks, sometimes culverted underground.
How it is recognised
Rivers, streams, canals, ditches
Structures such as culverts and spillways
Main rivers versus ordinary watercourses in law
