WAM Development History• 1984 - 1st GIS watershed model “Basin” developed for
Kissimmee River, FL (UF / COE) • 1988 - Basin New Zealand (BNZ) GIS watershed model
(UF/SWET/NIWA)• 1988-96 - Multiple upgrades of BNZ (UF/SWET)• 1997 - First release of the Watershed Assessment Model - WAM
for Suwannee River WMD (SWET/Mock•Roos)• 1998 - Daily routing option of WAM released SJR-WAM• 2000 - WAMView Release (ArcView version of WAM Model)• 2000 - WAM-O(Okura Catchment) release in New Zealand • 2001-04 – Multiple upgrades of WAM
