Factors Contributing to Water and Wind Erosion of Soil

Objective

By the end of this section the student/user will be able to:

Identify and analyze factors contributing to water and wind erosion of soil

Accompanying Exercise: (For students to print off, complete, and turn in for a grade)

Factors Contributing to Water and Wind Erosion of Soil- Exercise (pdf)

Climate, soil properties, vegetation, soil cover, and land management practices are factors that influence both water and wind erosion. Soil surface roughness, unsheltered distance, and wind velocity and turbulence are additional factors influencing wind erosion, and topography is an additional factor influencing water erosion.

Factors Influencing Erosion
Water Erosion	Wind Erosion
climate	climate
soil properties: aggregation /soil moisture	soil properties
soil cover	soil cover
land management	land management
topography	soil surface roughness
	unsheltered distance
	wind velocity and turbulence

The following six pages will discuss each of the factors contributing to water and wind erosion.
