This interface allows the WEPP watershed model to be set up and run using a web browser. The simulations are run on servers at the NSERL and model results displayed in Google Maps. Model output includes spatial soil loss and runoff for small watersheds.
The WEPP online GIS interface uses OpenLayers, MapServer and Google images to provide a seamless approach to defining a watershed for simulation with WEPP.
