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 dams and their types and purposes, describe design, safety and operation, present environmental and social debates with attribution, and identify specific dams with sources.

A barrier built across a river, stream or estuary to hold back water for storage, flood control, irrigation, water supply, navigation or hydroelectric power, in forms from earth and rock-fill embankments and concrete gravity and arch dams to tidal barrages, small weirs and temporary log booms, and including historic and ruined dams; dams are major infrastructure with benefits and impacts on rivers, ecosystems and communities, and are designed, operated and regulated for safety.

What it is for: Barriers holding back water.

It can be explain types and purposes; describe design and safety; present debates; identify specific dams.

Distinguishing features

Impoundment

Structural types

Multiple purposes

Safety regulation

What it looks like

A wall or embankment across a river with a reservoir behind.

How it is recognised

Barrier impounding water

Embankment, gravity, arch or barrage

A levee runs alongside a river; a weir is low and overflowed
