Models are contained within a GIS-linked system called Basins (Better Assessment Science Integrating Point and Nonpoint Sources). GIS database for HUC units in the US linked to:

HSPF-NPSM (Hydrologic Simulation Program Fortran – Nonpoint Source Modeling)

QUAL2E – steady state water quality modeling in rivers

Toxiroute – unsteady state water quality routing

Basins 3 is in beta testing and it has the SWAT model in it.

Assignment for Tues Jan 23:

Divide up into groups of two people with each group picking a different website. Prepare a brief presentation to the class with a brief one or two-page handout which describes what modeling systems are available at that site, what problems the models solve and how one might obtain their input data.
