Global assessment of wind erosion based on a spatially distributed RWEQ model

Progress in Physical Geography: Earth and Environment, 2021
Wind erosion is a global environmental problem and affects the sustainable use of land soil. The current efforts in wind erosion modeling mainly focus on local scales, yet very few studies have attempted to quantify the soil losses by wind on a large scale.

Study on Influencing Factors of Soil Wind Erosion Modulus Based on RWEQ Model

Open Journal of Soil and Water Conservation, 2023
The RWEQ model is a key model for the quantitative study of soil wind erosion. In order to deeply analyze the relationship between each introduced variable and soil wind erosion in the modelling process of this model, the maximum soil transfer capacity ...

Study on the Relationship between Soil Particle Content and Soil Erodibility Based on RWEQ Model

Hans Journal of Agricultural Sciences, 2023
In order to study the relationship between soil particle content and soil erodibility factor EF value, based on the RWEQ model, the integer combination data sets of soil particle content from 1% to 98% and silt, clay and sand content of 1%, 2%, 10%, 30%,

RWEQ: Improved wind erosion technology

Journal of Soil and Water Conservation, 2000
: An improved wind erosion model (RWEQ) has been developed and validated with field erosion data from 45 site years. In RWEQ, the residue, soil erodibility, and soil roughness parameters are represented as coefficients.

Soil roughness for the revised wind erosion equation (RWEQ)

Journal of Soil and Water Conservation, 1999
: Soil surface aggregates (random roughness) and ridges (oriented roughness) can reduce soil loss by wind erosion. The soil roughness factor used in the Wind Erosion Equation (WEQ) model describes the effect of soil roughness on soil loss by wind ...

Validation of the Revised Wind Erosion Equation (RWEQ) for Single Events and Discrete Periods

Soil Erosion, 2013
The Revised Wind Erosion Equation (RWEQ) makes annual or period estimates of wind erosion based on a single event wind erosion model that includes factors for wind and rainfall, soil roughness, the erodible fraction of soil, crusting, and surface residues. In this study we measured wind erosion and the factors used in RWEQ for 41 storm events at six
