2008 Annual Report

1a.Objectives (from AD-416)
The Wind Erosion Prediction System (WEPS)is being developed in response to requests for improved erosion prediction technology for use by NRCS, as well as other government agencies and conservation partners. ARS has signed an Agreement with NRCS detailing the delivery and testing of WEPS 1.0 within their agency. Delivery of WEPS 1.0 includes delivery of documented code and working with NRCS in a staged testing process that insures the product meets NRCS requirements to the field office level. The WEPS 1.0 code documentation consists of a) technical documentation for all science modules and b) full JavaDoc for all interface code. The support required for the staged testing process includes programming support for a) all science code changes needed to meet tester identified science issues and b) all interface changes needed to meet tester identified usability issues.

1b.Approach (from AD-416)
We are in the second year of a two-year Agreement between ARS and NRCS detailing the testing and delivery of WEPS 1.0 to NRCS. We are now entering the second phase of NRCS testing and review. Issues that are identified during this regional testing phase need to be addressed in a timely manner. Needed interface fixes identified by testers will be addressed before the next testing session. Complete JavaDoc compliant documentation for all interface code elements will also be completed, allowing NRCS to maintain the code as necessary. 05-IA-5430-0324

3.Progress Report

a. Enhanced the WEPS Run Summary Report to include crop yield/harvest residue information and a list of the operations (with dates) in the management rotation. b. Cleaned up the operation and crop drilldown screens to display only the pertinent elements necessary for NRCS usage of WEPS. c. Improved the ability to save WEPS runs into any specified directory location. d. Improved graphic depiction of field drawings. e. Provided PDF versions of output reports for archival and printing purposes. f. Incorporated NRCS Energy Calculator and Soil Conditioning Index (SCI) routines into WEPS. g. Enhanced the WEPS Management/Crop Rotation Editor (MCREW) to make it easier to import and use RUSLE2 derived management rotation files. h. Cooperated in expanding and maintaining the WEPS climate and wind databases in cooperation with other USDA personnel. i. Updated WEPS 1.0 science and interface technical documentation as needed based on model changes. j. Provide technical support to NRCS throughout the NRCS WEPS implementation and training period, including addressing any bugs or other problems with the WEPS 1.0 model and related software. k. Kept the NRCS Responsible Person (Mike Sporcic) informed of any changes to WEPS 1.0. l. Made numerous interface improvements and bug fixes based upon feedback from NRCS during the training phase of NRCS WEPS implementation.

Methods used to monitor this project included, discussing project plans, reviewing program goals and accomplishments with the Cooperator’s PI at ARS and NRCS facilities; by teleconference, e-mail or other types of written correspondence; providing technical advice to Cooperator’s personnel; and, conducting site visits at Cooperator’s facilities.
