Baseline land cover was from the NLCD2011 database. IPCC SRES scenarios (https://www.ipcc.ch/site/assets/uploads/2018/03/sres-en.pdf) interpreted by Sohl et al. (2014) (https://doi.org/10.1890/13-1245.1) for the conterminous United States were downscaled from 250 meters to 30 meters. The baseline and scenario land cover data were used as input into the Soil Water and Assessment Tool (SWAT) model to assess the effect of outyear projected land cover change on the source of raw water for the city of Minneapolis, MN. SWAT was used to assess the effect of land cover change raw water concentrations of sediment, total nitrogen, and total phosphorus. The IPCC SRES evaluated were A1B, A2, B1, and B2. The four scenarios were implemented with (A1Bf) and without (A1B) forest recovery (e.g., conversion of cropland (2011) to forest (2050) for a total of eight scenarios. The LULC net change file reports total change in hectares between 2011 and 2015 for forest, developed, cropland, pastures, and wetland for the four IPCC SRES scenarios with and without forest recovery.

Photogrammetric Engineering and Remote Sensing 81:345-354); SWAT is a spatial water quality model. Map coordinates are based on an Albers conical equal area projection. Projection parameters: false_easting (0.0); false_northing (0.0); central meridian (-96.0); standard parallel 1 (29.50); standard parallel 2 (49.50); latitude of origin (23.0); linear unit (meter); geographic coordinate system (GCS North American 1983); datum (D North American 1983); prime meridian (Greenwich); angular unit (degree). Watershed area is approximately 50,000 sq. km.
