Thanks Ismail Mondal for adding useful information.

I don't know if this might be helpful, but I don't remember reading, learning about erosion orders. There are various types or forms of erosion. Typically, use of new terms or classification has some basis to refer back to, to describe the intent of the terms. Articles that use the reference to erosion orders should either define their use or cite a reference. There are many forces that can cause or contribute to erosion, so unless you find or have regular uses of the erosion orders, or a suitable reference, I would just carefully read the articles in hope of determining what the author is referring to. Perhaps someone knows of a reference, and where a discussion about erosion orders would be part of normal or standard scientific discourse, so I plan to check back on other responses .

Dear Asad,

The three stages of soil erosion are: (1) dislodgement, (2) transportation, and (3) sedimentation.

Soil cover dramatically affects dislodgement by protecting the soil from raindrop impact.

Soil cover also reduces transportation by providing physical barriers and opportunities for ponding and velocity reduction. Infiltration affects transportation. Hence a soil with high infiltration will have less transportation.

Sedimentation occurs when the velocity and carrying capacity of runoff decreases. This may happen if soils change in slope or infiltration capacity.

Montier et al. (1998) developed an expert-based method for France. As with CORINE, the method is based on scores that are assigned to factors related to land cover (9 classes), the soil’s susceptibility to surface crusting (4 classes), slope angle (8 classes) and erodibility (3 classes).

With the Erosion Potential method of Gavrilovic (1962) you have 5 classes of Erosion intensity (1) Very low; (2) Low; (3) Moderate; (4) High; (5) Very high.

(1) Very low, Z value < 0.20; (2) Low, Z value 0.20~0.40; (3), Moderate, Z value 40~0.70; (4) High, Z value 0.70~1.00; (5) Very high, Z value > 1.00.

Thanks Velibor Spalevic for providing informative answer regarding the issue under consideration.
