How do you calculate wind erosion?
§ 610.13 Equations for predicting soil loss due to wind erosion.
- (a) The equation for predicting soil loss due to wind in the Wind Erosion Equation (WEQ) is E = f(IKCLV).
- (b) [Reserved]
- (c) The factors in the WEQ equation are defined as follows:
- (1) E is the estimation of the average annual soil loss in tons per acre.
What are the factors affecting water erosion?
Climate, soil properties, vegetation, soil cover, and land management practices are factors that influence both water and wind erosion….Objective.
| Factors Influencing Erosion: | |
|---|---|
| Water Erosion | Wind Erosion |
| climate | climate |
| soil properties: aggregation /soil moisture | soil properties |
| soil cover | soil cover |
What is meant by sheet erosion?
Sheet erosion occurs as a shallow ‘sheet’ of water flowing over the ground surface, resulting in the removal of a uniform layer of soil from the soil surface. Sheet erosion occurs when rainfall intensity is greater than infiltration (sometimes due to crusting).
What are the two types of wind erosion?
Wind erosion uses two main mechanics: abrasion and deflation. Deflation is further broken down into three categories: surface creep, saltation and suspension.
What are the 3 steps of erosion?
Erosion involved three processes: detachment (from the ground), transportation (via water or wind), and deposition. The deposition is often in places we don’t want the soil such as streams, lakes, reservoirs, or deltas.
How does wind erosion affect the value of soil?
The soil weight greatly affects the effect of the erosion. Lighter particles can be carried away by the wind. As the soil particles get heavier, they can just coast along the soil. This heavy soil can break down because of this, and be carried away, as well as break down other soil particles.
How does wind contribute to soil erosion?
High winds can contribute to soil erosion, particularly in dry weather periods or in the arid and semi-arid (ASAL) regions. The wind picks up the loose soil particles with its natural force and carries them away to far lands, leaving the soil sculptured and denudated.
Why is the wind agent of soil erosion?
Wind erosion is a natural process that moves soil from one location to another by wind power. It can cause significant economic and environmental damage. Wind erosion can be caused by a light wind that rolls soil particles along the surface through to a strong wind that lifts a large volume of soil particles into the air to create dust storms.
