U.S. Forest Service national riparian areas base map for the conterminous United States in 2019

This metadata record describes 10-meter raster riparian areas for 50-year flood heights for the conterminous United States in 2019. Fifty-year flood heights were estimated using U.S. Geological Survey (USGS) stream gage information. NHDPlus version 2.1 was used as the hydrologic framework to delineate riparian areas. The U.S. Fish and Wildlife Service’s National Wetland Inventory and USGS 10-meter digital elevation models were also used in processing these data.
