Water Erosion Prediction Project
Using Climate data in WEPP Windows
Breakpoint Climate Generator
Cligen parameter files for about 2600 stations in the US are included in the install package.
12/11/2008 - Cligen PAR file documentation for wind speed and wind speed standard deviation should be stated in units of m/s. In addition to the input file for Cligen (PAR file), the Cligen output file and WEPP model use units of m/s for wind speed. The corrected Cligen PAR file documentation is available here. The WEPP model, Cligen model and climate data files have not changed.
Soil parameter inputs for WEPP are based on 1992 SOILS-5 data. The install package includes soil archive files for each state. These archives can be used with the WEPP Windows Interface by selecting the Tools menu and then Soil Archive Program.
Example managements for agriculture, rangeland and forest are included in the install package.
A Web browser interface to WEPP model. Run WEPP simulations without having to download the software, simulations are run on servers at the NSERL.
Forest Service WEPP interfaces.The US Forest Service has developed specific web based interfaces for western forest and logging activities.
A GIS interface GeoWEPP, is available for WEPP. This is an ESRI ArcGIS extension that uses DEM data to derive topography inputs for WEPP.
DOS Interface file builders for WEPP. (1995) This software is no longer being updated but is available for download.
WEPP Validation Data Sets. For use with WEPP model (without interface), for hillslope and watershed.
CPIDS.(1997) Crop Parameter Knowledge Based System. CPIDS was developed to assist crop database builders and users of RUSLE and WEPP in interpretation of plant characteristics and selection of plant parameters. RUSLE, WEPP and other erosion prediction and natural resource models require detailed input parameters including those describing cropping systems. This software is no longer being updated but is available for download.
