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 erosion by agent, rate, impacts and control measures.

The removal and transport of soil, rock or dissolved material by natural agents such as water, wind, ice and gravity, including soil erosion, fluvial, coastal, wind and glacial erosion and downhill creep.

What it is for: A natural process shaping landscapes; accelerated erosion is a land management problem.

It can be measure erosion rates; control soil erosion on farms; protect coasts and riverbanks; interpret landforms.

Distinguishing features

Removal and transport of material

Driven by water, wind, ice and gravity

Natural and human-accelerated

Opposite of deposition

What it looks like

Gullies, cliffs, bare soil, muddy runoff and retreating coastlines.

Physical character

tolerable soil loss: about 1 t/ha/yr - often cited in Europe; varies

How it is recognised

Rills and gullies

Cliff retreat and undercutting

Deposition is the opposite process

What the second pass must settle

  • Should erosion types be separate entries?
  • How should erosion data be linked?
  • How should coastal management be linked?
