Please note that the AVGWLF watershed modeling software that has been available since 1999 (including GWLF and PRedICT) will no longer be updated. It is being replaced by MapShed, which essentially duplicates the functionality of AVGWLF within a non-commercial GIS software environment called MapWindow (see www.mapshed.psu.edu). Both the MapWindow software, as well as the customized interface and related modeling tools associated with MapShed, are available for download via this site. Within MapShed, the core watershed model (GWLF) has also been considerably enhanced to provide additional capabilities not included in the older version of the model used in AVGWLF. During a brief transition period, both AVGWLF and MapShed will be made available to potential users. However, it is expected that AVGWLF will be discontinued by mid-2012. Consequently, users are encouraged to start making the switch to MapShed at their earliest convenience.
