The current verison of the interface uses OpenLayers, MapServerand Google images

to provide a seamless approach to defining a watershed for simulation with WEPP. 


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.



Results of USDA-NSERL WEPP-GIS Channel Generation

To determine the watershed area that drains to the outlet point click on the Build Subcatchments button.



Review the watershed soils, landuse, channels.

WEPP Model Results (Saved)


As part of saving the project temporary files were deleted.

Rerun the WEPP simulation to recreate the output files.

Save the text to a file on your desktop (be sure to give it a meaningful name).


When returning to the online WEPP GIS interface paste the text into the load project screen to recreate the watershed.

Note that managements and soil setting are not saved so these will have to be reentered.
