Wind Erosion Prediction System (WEPS): Overview
Introduction 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 (WEQ) (Woodruff and Siddoway, 1965) as a prediction tool for those who plan so...
متن کاملThe Prediction of Horizontal Soil Fluxes During Wind Erosion Events
The horizontal flux of soil above eroding surfaces is often claimed to be proportional to a power of the friction velocity (or some other measure of the strength of the eroding wind field), with by far the most popular value of the power being 3. However, there is considerable variation between both the “goodness of fit” of a power law and the value of the power obtained from different data set...
متن کاملAn Overview of the Wind Erosion Prediction System
The Wind Erosion Prediction System (WEPS) is a process-based, daily time-step, computer model that predicts soil erosion via simulation of the fundamental processes controlling wind erosion. WEPS can calculate soil movement, estimate plant damage, and predict PM-10 emissions when wind speeds exceed the erosion threshold. It also can provide the user with spatial information regarding soil flux,...
متن کاملA Field test of the Wind Erosion Prediction System
Field data need to be collected to test wind erosion models under a broad range of climate, soil, and management conditions. The objective of this study was to test the USDAARS Wind Erosion Prediction System (WEPS) for a field with winter wheat plants in a modest amount of flat residue. A 600 m by 415 m field was selected near Burlington, CO, USA. Big Spring Number Eight (BSNE) samplers were us...
متن کاملAn Assessment of Wind Erosion Schemes in Dust Emission Simulations over the Middle East
Extended abstract 1- INTRODUCTION Atmospheric aerosols, solid and liquid particles in the atmosphere, play a crucial role in the atmospheric radiation equilibrium. These particles have an influence on the scattering and absorption of short wavelength radiation, and on the other hand, affect radiation absorption and emission in long wavelengths. Dust particles are among the importan...
