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 rivers by name, course, flow, water quality, flood risk, uses and cultural significance.

A natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river, with a source, course, tributaries and mouth; rivers can form borders and many are sacred or culturally significant.

What it is for: Water supply, ecosystems, transport, energy, recreation and culture.

It can be find source, course and length; check flow and flood warnings; check water quality; plan safe recreation.

Distinguishing features

Natural flowing water

Source, course and mouth

Drains a basin

Floods naturally

What it looks like

A channel of flowing water between banks, from streams to broad rivers.

Physical character

length: a few km to over 6500 km - major rivers such as the Nile and Amazon

discharge: under 1 to over 200000 m3/s - Amazon is the largest

How it is recognised

  • How should basins be linked?
  • How should transboundary disputes be represented?
