Second, to evaluate the risk of wind erosion during the most critical period of fallow using estimated values of soil losses from the Wind Erosion Equation (WEQ) (Woodruff and Siddoway 1965).
(1994) is used in the Revised Wind Erosion Equation (RWEQ) (Fryrear et al.
Basic Assumptions of the Revised Wind Erosion Equation
This study was conducted to develop a new soil roughness factor (K[prime]) for the Revised Wind Erosion Equation (RWEQ) model which (1) includes both oriented and random roughness effect; (2) is modified as rainfall decays the soil surface roughness; and (3) is predicted at any given angle with respect to ridge orientation.
Solving the functional relationships of the wind erosion equation as presented by Woodruff and Siddoway required the use of tables and figures.
The Revised Wind Erosion Equation (Fryrear and Saleh 1994) uses an empirical approach similar to RUSLE's, but for wind erosion.
Progress in revisions of USLE (now RUSLE) were highlighted and prospects of the Water Erosion Prediction Project (WEPP), Wind Erosion Prediction System (WEPS), and anticipated improvements in the wind erosion equation (now RWEQ) were discussed.
In the past, wind erosion losses have been estimated by the Wind Erosion Equation (WEQ) (Woodruff and Siddoway).
Dry sieving of soil with a compact rotary sieve is the technique recommended for determining wind erodible fraction of agricultural soils for use in the wind erosion equation (6, 11).
The Wind Erosion Equation currently used by SCS for estimating soil loss due to wind erosion involves an estimate of total weight of flat and standing above-ground residues and then a conversion of total weight to weight of flat Small Grain Equivalent (SGe) residue.(1) Accuracy of the conversion to SGe relies on the initial estimate of standing residues.
