A Wind erosion equation or WEQ is an erosion model designed to predict long-term average annual soil losses from a field having specific characteristics. The equation is: E = f(IKCLV) where E = Estimated average annual soil loss expressed in tons per acre per year I = Soil erodibility index K = Soil ridge roughness factor C = Climatic factor L = Equivalent unsheltered distance across the field along the prevailing wind erosion direction V = Equivalent vegetative cover
