rill erosion

rill erosion

[′ril i′rō·zhən]
(geology)
The formation of numerous, closely spaced rills due to the uneven removal of surface soil by streamlets of running water. Also known as rilling; rill wash; rillwork.

Although actual soil loss is underestimated since inter-rill erosion is excluded when measuring pipe, gully, and rill erosion, the approach produces the best approximation of erosion (Bewket and Sterk, 2003).
With regard to environmental impacts, analyses conducted using the Revised Universal Soil Loss Equation 2 (RUSLE2) and USEtox models indicated that sheet and rill erosion were on average 28% lower in the LEI systems than in conventional system, and that over the last six years of the experiment, herbicide-related aquatic toxicity potential was more than 200-fold lower in the LEI systems than in the conventional system.

drop size, intensity and kinetic energy); plot runoff frame size and installation; runoff sampling size, frequency and duration; the identification of plot cover, slope and surface soil conditions; the measurement of inter-rill erosion, rill erosion or combinations; plot replication or the degree to which plots represent hill slope conditions; and the interpretation of runoff sediment sampling relative to local soil, cover and climate conditions.
Eroding features are dominantly formed by splash, flow areas are formed by interrill erosion, while pre-rills and rills indicate the degree of rill erosion (Bergsma, 2008).
Regardless of changes in CN, and the coefficient of runoff, development of water erosion, especially surface erosion, rill erosion, gully erosion and piping erosion were visible in the visit of the area, which can attribute their recent development to their increase amount of surface runoff and discharge, although this may be arise from climate changes, natural factors and other factors.
They used techniques that can tell them whether the sediment originated as channel and gully erosion, or as shallow sheet or rill erosion further up hillslopes.
Ephemeral gullies are common features on agricultural landscapes and can sometimes lead to soil losses that exceed losses from sheet or rill erosion.
Among the most troubling effects of increased precipitation intensity on runoff and soil erosion will be beginning to shift the dominant processes causing damage from sheet and rill erosion to concentrated flow erosion in ephemeral or permanent gullies.
