Data from the web
New and updated datasets (see metadata) have been added to the data download directory for each 8-digit watershed or HUC in the lower 48 states, Alaska (19), Hawaii (20), and Puerto Rico with the U.S. Virgin Islands (21). Data by HUCs can be found on the web. Use "Surf Your Watershed" to find and locate HUCs.
The DEM (Digital Elevation Model) shapefile and grid datasets can be added to BASINS before or after the BASINS project has been created.
The National Elevation Dataset (NED), a higher resolution elevation grid, tiled by HUC boundary is also available.
The GIRAS landuse/landcover has been removed from the core data and is now available seperately as a shapefile for each HUC.
Weather data by states for the models can be found at /ost/ftp/basins/wdm_data/.
The SWAT model in BASINS requires STATSGO data.
