coastal sediment transport, sandfall, sediment gravity flow

What it is Filled

The movement of solid particles by water, wind, ice or gravity, from river bedload and suspended load and coastal sediment transport along shores by waves and currents to sediment gravity flows such as turbidity currents and debris flows and underwater sandfalls where sand cascades down submarine slopes; sediment transport shapes rivers, coasts and seabeds and is central to engineering of harbours, dams and beaches.

Why it exists Filled

Let an agent explain sediment transport and its modes, relay physics, measurement and modelling from geomorphology and engineering sources, describe coastal transport and gravity flows, and distinguish sediment transport from erosion, deposition and sediment as material.

Distinguishing features Filled

  • Fluid and gravity driven
  • Bedload and suspension
  • Coastal and submarine
  • Engineering relevance

What robots and AI may and may not do Filled

Must not

  • Present model results for a coast or harbour as certain where the data is thin.
  • Recommend works that shift erosion onto a neighbouring shore without saying so.
  • Approve dredging or beach nourishment without the required permits and assessments.
  • Ignore risks to seabed cables and pipelines from gravity flows in a route assessment.

Only with a human decision

  • Approving coastal works, dredging or nourishment schemes.
  • Issuing erosion or landslide risk warnings to residents.

May

  • Model and report sediment transport for a river, coast or seabed from survey data.
  • Flag siltation, scour or erosion trends to the authority responsible.

Moral aspects Filled

  • Coastal erosion takes homes and land, and works that protect one shore often harm the next.
  • Debris flows and turbidity currents kill people and cut communications.

Who is affected

  • Coastal residents
  • Port and cable operators
  • Downstream communities

Owners Filled

Steward

Nobody owns the process; coastal and river authorities answer for works and monitoring.

Master systems

  • Hydrographic survey records
  • Coastal monitoring programmes

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.sediment-transport
  • Wikidata: Q7445303 (https://www.wikidata.org/wiki/Q7445303)

Direct properties not applicable Not applicable

  • Shields parameter: threshold of motion note
  • longshore transport rates: up to about 1 million cubic metres per year note - on energetic coasts

Plane ACT: no invented physical properties.

Recognition optional Filled

  • Movement of sediment by fluids and gravity
  • Bedload, suspended load, coastal sediment transport, sediment gravity flow, sandfall
  • Erosion detaches; deposition settles; sediment is the material
  • Not a visible object; moving sand, silt and gravel.

Capabilities and actions required Filled

  • explain modes and physics
  • relay measurement and modelling
  • describe coastal and gravity flows
  • distinguish related processes

Hazards and failure modes required Filled

  • Coastal erosion and harbour siltation
  • Turbidity current damage to cables
  • Confusing transport with erosion or deposition

Standards and interfaces required Filled

  • Coastal and river engineering guidelines
  • Dredging and beach nourishment regulations

Context of use required Filled

  • Not applicable; a geological process.
  • fluvial bedload and suspended load transport
  • aeolian transport
  • glacial transport
  • coastal and longshore sediment transport
  • sediment gravity flows such as turbidity currents and debris flows
  • submarine sandfalls and canyons

Sources Filled

  2. Wikipedia: Sediment transport - general description of the item

Open questions

  • Should coastal sediment transport and turbidity current be separate primary entries?
  • How should geomorphology and engineering sources be linked?
  • The registry entry has merged aliases naming modes and a submarine feature; should they be split off?
