What it is Filled
A low area of land between hills or mountains, typically with a river or stream flowing through it, formed by processes including river or glacial erosion and tectonic movement; types include V-shaped, U-shaped, rift and dry valleys, and valleys on other planets.
Why it exists Filled
Let an agent handle valleys by name, type, formation, hazards and use.
Distinguishing features Filled
- Elongated depression between higher ground
- Often river-formed
- Glacial valleys are U-shaped
- Found on other planets as chasmata
What robots and AI may and may not do Filled
Must not
- Understate flood or slope hazards in a valley when advising on building or travel.
- Divert or dam a valley watercourse without lawful authority.
- Guide people into a valley under a flood or avalanche warning.
Only with a human decision
- Ordering evacuation of a valley.
- Approving construction on a valley floor.
May
- Describe a valley's landforms, rivers and settlements from maps and surveys.
- Monitor and report flood, landslide or avalanche risk for an authority that authorized it.
Moral aspects Filled
- Valleys concentrate floods and debris flows; warnings save lives.
- Dams and diversions in valleys displace communities and affect people downstream.
Who is affected
- Residents
- Downstream communities
- Ecosystems
Owners Filled
Steward
Landowners and the public; planning and water authorities govern use.
