Maintaining vegetative cover on the soil surface is the most widely used method for control of soil loss by wind erosion. We numerically modeled airflow through artificial standing vegetation (i.e., simulated wheat plants) using computational fluid d

Deciduous trees of the species (Osage orange) are commonly established as vegetative barriers for wind erosion control throughout the U.S. Great Plains. Because there is no previous research on the aerodynamic effectiveness of these vegetative barrie

Little is known about the dust removal efficiency of common vegetative barriers. This study of blowing dust reduction was conducted on one of the most common vegetative barriers used for wind erosion control in Kansas and the U.S. Great Plains, the d

Crop residues help protect topsoil from depletion and abrasion due to wind erosion. Limited studies have focused on the type and orientation of canopies that help minimize the effects of erosion by wind. In this study, a series of wind tunnel experim

During significant wind erosion events, the soil surface is continually modified; however, erosion models rarely account for these changes. The objectives of this work are to provide an overview of the WEPS soil surface update methodology and demonst

Soil Erosion and Crop Productivity
Conditions conducive to wind erosion exist when the soil is loose, dry, and finely granulated; the soil surface is smooth and vegetative cover is sparse or absent; the susceptible area is sufficiently large; and the wind is strong and turbulent enoug

The Wind Erosion Prediction System (WEPS) is a process-based model that simulates daily weather and field conditions along with hourly wind speeds and erosion. Its physical basis should allow model application to regions outside the US for which it w
