Interpretive Summary:

Technical Abstract: Typical wind erosion studies have primarily looked at mass flux rates and soil loss from source locations. Correspondingly, wind erosion prediction models have historically focused on those same elements. Thus, most wind erosion control measures have been designed for and evaluated based upon their cost effectiveness at mitigating onsite impacts. Yet, the true costs sof wind erosion events are often those that occur offsite. With the adven of the Wind Erosion Prediction System, (WEPS-a physically based, daily time step wind erosion model) many offsite impacts of wind erosion can now be successfully explored and addressed. Two examples of offsite wind erosion impacts, filling of roadside drainage ditches and reduced visibility along roadways are examined. These examples focus on how WEPS can benefit in the design and/or selection of effective practices for controlling these offside wind erosion effects.
