Wind Erosion Equation definition

Wind Erosion Equation means the mathematical formula for estimating or predicting average annual soil erosion rates due to wind erosion, as described in Section I of the Technical Guide.

Examples of Wind Erosion Equation in a sentence

  • The potential average annual rate of wind erosion is estimated by multi- plying the following factors of the Wind Erosion Equation (WEQ): Cli- matic characterization of windspeed and surface soil moisture (C) and the degree to which soil resists wind ero- sion (I).

  • The equation for predicting soil loss due to wind in the Wind Erosion Equation (WEQ) is E = f(IKCLV).

  • Skill in applying approved erosion prediction technology (Revised Universal Soil Loss Equation and the Wind Erosion Equation).

  • The first Wind Erosion Equation (WEQ) to quantify wind erosion was published by Woodruff and Siddoway in 1965.

  • A more process-oriented Wind Erosion Prediction System (WEPS) is under development (Hagen, 1991).Fryrear and colleagues describe a Revised Wind Erosion Equation (RWEQ) based on the parameters wind force, surface roughness, soil wetness, and crop residue or crop canopy.

  • WEPS has been designated to replace the more empirical Wind Erosion Equation (WEQ) currently used by the USDA Natural Resources Conservation Service (USDA‐NRCS).Wind is the principal driver of WEPS.

  • Average annual rates of erosion are estimated (for NRI data points) using the Universal Soil Loss Equation (USLE; Wischmeier and Smith, 1978) and the Wind Erosion Equation (WEE; Skidmore and Woodruff, 1968).

  • Complete worksheets, including Dairy Pond Sizing Software, Leaching Index, Phosphorus Index, Wind Erosion Equation, RUSLE2, to determine pond size and ensure quality criteria has been met for resource concerns for planned resource management system.

  • A Wind Erodibility Index (“I” factor) was subsequently developed as an expression of dry soil aggregate stability under tillage and abrasion for the Wind Erosion Equation (WEQ), an empirical equation to estimate potential soil loss by wind (t ha−1 yr−1) (Woodruff and Siddoway, 1965).The WEGs and “I” factor are used by managers globally as indicators of soil erodibility (NRCS, 2018).

  • The Wind Erosion Equation (WEQ) (Woodruff and Siddoway, 1965) is the main erosion prediction technology currently in use.
