2008 Annual Report 1a.Objectives (from AD-416) Complete the WEPS 1.0 user documentation suite, which consists of; (a) WEPS 1.0 user's Guide; (b) WEPS 1.0 tutorials; (c) DVD training session on fundamental wind erosion processes; (d) online, context-sensitive help; and (e) presentation materials to assist in training WEPS 1.0 users. 1b.Approach (from AD-416) Both parties are interested in developing documentation for WEPS 1.0 that will not only assist in training users to correctly apply the WEPS model, but also provide the WEPS user with basic information on the fundamental physical processes of wind erosion as well as the underlying principles and strategies for its control. This information will assist land managers, conservation partners, NRCS, and military personnel in controlling wind erosion on agricultural crop lands, disturbed lands and natural ecosystems. Both parties already have ongoing research efforts in wind erosion; and, the cooperative work to be conducted under this SCA will be collaboratively planned and conducted. 3.Progress Report a. Updated WEPS 1.0 science and interface technical documentation as needed based on model changes. b. Made numerous interface improvements and bug fixes based upon feedback from NRCS testers/reviewers during the second phase of NRCS WEPS testing and the pre-implementation phase during the “train-the-trainer” sessions. c. Added and then revised the "PDF format" reports for WEPS, which will allow NRCS to more easily print and archive results from WEPS simulation runs. d. Improved the ability to save WEPS runs into any specified directory location. Eliminated the term "Project" and replaced it with the concept of "Client" for NRCS field office usage. The "P" and "T" buttons have been removed and dropdown choice lists replace their functionality for NRCS field office usage. e. Incorporated the NRCS Energy Calculator and Soil Conditioning Index (SCI) routines into WEPS and developed specialized reports for them. f. Provided methods to "lock" databases so users cannot edit the data, except for specific elements identified for "temporary edits for a specific calculation". g. Assisted in expanding and maintaining the WEPS climate and wind databases in cooperation with other USDA pesonnel. Provided automated access to cligen and windgen stations based upon GIS maps fo regions outlined by NRCS personnel for use in their field offices. h. Assisted in validating crop records in cooperation with NRCS personnel by making WEPS runs in locations and on soils with typical management practices used where the crops are commonly grown.
