Dear WEPP User:

A new WEPP model executable is now available which fixes several bugs that
were identified in WEPP model version 98.4. The new WEPP model is version
99.5, and contains corrections to output, date handling (simulation year 
instead of calander year), corrections to OFE output, addition of sediment
leaving an OFE to the large graphics output file as well as other fixes.
There is also a new management option for residue additions, which can be
utilized via the windows interface (not available via the DOS interface).
Contour set start and end dates have been modified in the Fortran model,
but setting of this option is currently not available via either the DOS
or Windows interfaces.

To do a minimum install the of the WEPP 99.5 program and DOS interface, 
transfer the following files to a temporary directory on your PC:

 INSTALL.EXE
 INSTALL.CFG
 NEWINFO.TXT
 WEPP995.SHR
 README.TXT

then run the INSTALL program.  If you need additional climate stations,
transfer the appropriate archive (ZZ97SE.EXE, etc.), before running the
install program.

WEPP Version 99.5 should work with any existing WEPP model simulation runs
which you have previously defined.

If you have any difficulties or need information or assistance, please contact:
