Wind Erosion Prediction System: Management Submodel 1

The Wind Erosion Prediction System (WEPS) is a process-based, daily time-step model that simulates weather, field conditions, and erosion. WEPS development is in response to customer requests for improved wind erosion technology. It is intended to replace the predominately empirical Wind Erosion Equation (Woodruff and Siddoway, 1965) as a prediction tool for those who plan soil conservation systems, conduct environmental planning, or assess offsite impacts caused by wind erosion. WEPS incorporates improved technology for computing soil loss by wind from agricultural fields as well as providing new capabilities such as assessing plant damage, calculating suspension loss, and estimating PM-10 emissions from the field (Wagner, 1996).
