Wind erosion is a serious problem on agricultural lands throughout the United States as well as the world.
The ability to accurately predict soil loss by wind is essential for, among other things, conservation planning, natural resource inventories, and reducing air pollution from wind blown sources.
The Wind Erosion Equation (WEQ) was widely used for assessing average annual soil loss by wind from agricultural fields.
The primary user of WEQ was the United States Department of Agriculture, Natural Resources Conservation Service (USDA-NRCS).
When WEQ was developed more than 55 years ago, it was necessary to make it a simple mathematical expression, readily solvable with the computational tools available at the time.
Since its inception, there have been a number of efforts to improve the accuracy, ease of application, and range of WEQ.
Despite these efforts, the structure of WEQ precluded adaptation to many wind erosion problems.

In the mid-1980’s, USDA appointed a team of scientists to take a leading role in combining the latest wind erosion science and technology with databases and computers,
to develop what would become a significant advancement in wind erosion prediction technology.
The Wind Erosion Prediction System (WEPS) incorporates this new technology and was designed to replace WEQ.
WEPS version 1.1.16 was eventually installed for use on 15,000 computers in 2200 NRCS Field Offices in October of 2010.
Several iterations of improvements to WEPS have resulted in multiple revision upgrades since then.
\WEPSver{} (or WebStart WEPS) is the current iteration,
which includes major updates since WEPS 1.5 to its databases, 
the addition of remote data access services and remote execution of WEPS simulations made in the cloud.

Unlike WEQ, WEPS is a process-based, continuous, daily time-step model that simulates weather, field conditions, management, and erosion. 
\WEPSver{} consists of the WEPS science model with a user-friendly interface that has the capability of simulating spatial and temporal variability of field conditions and soil loss/deposition within a field. 
\WEPSver{} can also simulate simple field shapes and barriers on the field boundaries.
The saltation/creep, suspension, PM10 and PM2.5 components of eroding material also are reported separately by direction in \WEPSver.
WEPS is designed to be used under a wide range of conditions in the United States and is adaptable to other parts of the world.  For further information regarding WEPS contact:
