This WEPP software consists of an erosion prediction model (WEPP) written in the Fortran programming language, a climate generator program (CLIGEN) also written in the Fortran programming language, and a Windows interface (WEPPWIN) written in the Visual C++ programming language. The interface accesses databases, organizes WEPP and CLIGEN simulations, creates all necessary input files for WEPP and CLIGEN, and executes the Fortran models when necessary. The interface also accesses and processes output information from the Fortran models for display and access by the user.

Section 1. WEPP Software Installation
The WEPP model and Windows interface can be installed from a file on a CD-ROM, or from the installation program downloaded from the NSERL web site. At the time of this document revision, the installation executable file was “wepp7-2002.exe”.
Use either Internet Explorer or Windows Explorer to locate the installation file “wepp7-2002.exe” on your CD-ROM drive or in the directory in which you downloaded it from the NSERL Web site. Use the mouse to double-click on the WEPPWIN.EXE file. This will start the installation process.
