flood
Let an agent handle floods by type, location, severity, warnings and response, and give safety information from official sources.
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 floods by type, location, severity, warnings and response, and give safety information from official sources.
An overflow of water onto land that is normally dry, from rivers, the sea, heavy rain, snowmelt or failed infrastructure; also a subject of flood myths.
What it is for: Floods are hazards to manage; understanding them supports warning, planning and recovery.
It can be forecast and warn of it; prepare for and respond to it; map flood risk; recover and claim insurance.
Distinguishing features
Water on normally dry land
Types: river, surface water, coastal, groundwater, flash
Warnings issued by official services
Among the most costly natural hazards
What it looks like
Water covering land, roads and buildings; rivers out of their banks; coastal inundation from storm surge.
Physical character
depth: centimetres to metres depth - 15 cm of fast water can knock a person over
return period: 1 in 10 to 1 in 1000 years - probability used in planning
How it is recognised
Water where land is normally dry
Official flood warnings and maps
Debris lines showing peak levels

- What does the warning level mean? definition
Protective actions
What to do.
Actions
Recommended actions.

Risk Planning and maps.
Risk maps guide planning and insurance.
Risk maps
Flood zones.

- Which defences protect this area? definition
- What standard of protection? measurement
Recovery After the flood.
Recovery has health and financial dimensions.

- Is drinking water safe? boundary
Support
Insurance and aid.
Support

- What insurance and aid are available? action
- How is damage documented? action
What the second pass must settle
- Should flood types be separate entries?
- How should agents present live warnings reliably?
- The registry entry has merged aliases naming specific floods; should they be split off?
