estuary
Let an agent explain estuaries, relay classification, ecology, human uses and threats from coastal science and conservation sources, describe mangrove estuaries, route tidal hazards, and distinguish estuaries from deltas, lagoons, bays, river mouths as points and fjords as a subtype.
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 estuaries, relay classification, ecology, human uses and threats from coastal science and conservation sources, describe mangrove estuaries, route tidal hazards, and distinguish estuaries from deltas, lagoons, bays, river mouths as points and fjords as a subtype.
A partially enclosed coastal body of water where fresh water from rivers mixes with seawater, influenced by tides, waves and river flow, classified by mixing as salt-wedge, partially mixed or well-mixed and by geomorphology as drowned river valleys, bar-built, fjords and tectonic estuaries, and including mangrove estuaries, named in a registry alias, in tropical regions; estuaries are highly productive nursery habitats for fish and birds and support ports and cities, but face pollution, dredging, habitat loss and sea level rise. Tidal currents and mudflats can be dangerous to visitors.
What it is for: Coastal habitat where rivers meet the sea.
It can be explain classification; relay ecology; relay human uses and threats; route tidal hazards.
Distinguishing features
Brackish water
Tidal influence
High productivity
Human pressure
What it looks like
Broad tidal waters with mudflats, salt marshes or mangroves where a river reaches the sea.
Physical character
Pritchard definition: 1967 year - widely cited
salinity range: from near 0 to about 35 psu - along the estuary
registry parents: river mouth, body of water, ecoregion note
How it is recognised
Mixing zone of river water and seawater
Mangrove estuary
Deltas build land from sediment; lagoons are separated by barriers; bays are coastal indentations; river mouths are points; fjords are glacial estuaries
