What it is Filled
A place where a river or stream flows over a vertical drop or series of steep drops, forming falls, cascades or cataracts; waterfalls are major natural attractions and also occur artificially and underwater in the sense of density currents.
Why it exists Filled
Let an agent handle waterfalls by name, height, flow, access and safety, including the dangers of swimming and slippery rocks.
Distinguishing features Filled
- Water over a drop
- Varies with season
- Popular attraction
- Hazardous rocks and currents
What robots and AI may and may not do Filled
Must not
- Encourage climbing, swimming or jumping at waterfalls where it is unsafe or banned.
- Fly drones over waterfalls in breach of local rules or near visitors.
- Disturb wildlife or erode paths at protected waterfalls.
- Present unofficial access routes as safe.
Only with a human decision
- Guiding visitors during floods or high water.
May
- Describe a waterfall's location, height and access from reliable sources.
- Report access closures and safety warnings from site managers.
Moral aspects Filled
- People die at waterfalls each year from falls and drowning.
- Popular falls suffer from crowding and erosion.
Who is affected
- Visitors and swimmers
- Rescue services
- Local communities
Owners Filled
Steward
The landowner or protected-area authority.
Master systems
- Land registry or cadastre

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.waterfall
- Wikidata: Q34038 (https://www.wikidata.org/wiki/Q34038)
Direct properties required Filled
- Vertical drop: m - Measure the elevation difference between the top and bottom of the specified fall or series of falls.
- Water discharge: m3/s - Determine the volume passing a defined river cross section per second and record the observation date because flow varies.
- Width of flowing crest: m - Measure the width of water crossing the waterfall crest under the recorded flow conditions.
Recognition required Filled
- Vertical drops and plunge pools
- Cascades, cataracts and horsetails
- Rapids are steep but without a drop
- Water falling over cliffs or steps, with spray and plunge pools.
Capabilities and actions required Filled
- find waterfall information and access routes
- check safety guidance at falls
- compare heights and flows from sources
- photograph waterfalls responsibly
Hazards and failure modes required Filled
- Falls from slippery rocks
- Drowning in plunge pools and currents
- Sudden flow increases after rain
Standards and interfaces required Filled
- Protected area rules
- Water safety guidance
Context of use required Filled
- Scenery, recreation, hydropower and ecosystems.
- plunge waterfalls
- cascades
- horsetail waterfalls
- tiered waterfalls
- artificial waterfalls
Sources Filled
- Wikidata item Q34038: waterfall - identity and sense of the item
- Wikipedia: Waterfall - general description of the item
Open questions
- Should waterfall types be separate entries?
- How should height data be sourced?
- How should safety closures be linked?
