Rill erosion definition

Rill erosion means a moderate level of erosion. Rill erosion is erosion rivulets greater than 1” but less than 12” in depth.

Rill erosion means erosion that cuts a number of small channels less than one foot in depth into the soil by water moving over and concentrating in low places in the soil surface.

Examples of Rill erosion in a sentence

  • Rill erosion means the removal of soil by runoff water to create small channels up to 30 centimetres deep.

  • Rill erosion of the soil surface tends to concentrate more flows, which then flow faster and gain erosive energy as a result of gravitational forces.

  • Rill erosion tends to occur on slopes, particularly steep slopes with poor vegetative cover.

  • Rill erosion is considered to most significant with up to fifty times more soil being lost through rilling than from other forms of erosion (ORC, 1995).

  • Rill erosion induced by moderate intensity rainstorms on finely cultivated soils can deposit 20–93 t/ha of sediment at the foot of cultivated slopes (Hunter et al, 1990).

  • Rill erosion is initiated when there is downward scour of the topsoil.This may occur where the surface is less resistant to particle detachment or where flow velocity is increased by an abrupt gradient change.

  • Rill erosion occurs when water from sheet erosion combines to form small concentrated channels (Fortuin, 2006).

  • Rill erosion of the soil surface concentrates flows, which increases flow velocity and erosive energy due to gravitational forces.

  • Rill erosion occurs as runoff begins to form small concentrated channels.

  • You must immediately forward any Data Subject request you receive to the Administration Department and comply with the company's Data Subject response process.
