RUSLE2 - Revised Universal Soil Loss Equation 2

• Transitioning from RUSLE2 to WEPP (PDF)
• Current Version: RUSLE2 Version 2.7.0.5 (November 4, 2021)

RUSLE2 version 2.7.0.5 has a known error when printing to a Word template. The error is not consistent between users or managements. Multi-year rotations appear to be more stable than managements with only a single year. The erosion, STIR, SCI, and surface residue calculations are correct within the program. The error is only a printing error in the management table which causes the output to appear invalid. The source of the error has been identified and a permanent solution is in progress.

Base Database vs. Database Update Files:

1. The base database, such as Base_NRCS_Moses_01292015, is more complete than the database update file and has all of the parameters necessary to run RUSLE2 except local data, including climate, soils, and crop management templates. When there is a major change in database, such as CMZs, soils, operations, or vegetations, particularly deletions, it is recommended to archive the working moses database and build a new working moses database. The active database in RUSLE2 becomes the current base database into which local soils, climates, CMZs, and c folder managements, profiles, worksheets and plans are imported.
2. The database update file, such as NRCS_Moses_updates_030104to01292015.gdb, is not a complete database but only contains new additions and edits since the initial release of RUSLE2 and therefore must be imported into the current local database using the database\import function in RUSLE2. This file should never be used as the starting database since incomplete. It is only used to import into a base database or working Moses database.
