Watersheds of Great Smoky Mountains National Park: a geographical information system analysis
Parker CR and Pipes DW. 1990. Watersheds of Great Smoky Mountains National Park: a geographical information system analysis. Research/Resources Management Report SER-91/01. National Park Service, Department of the Interior. Atlanta, GA
This report is the first of several describing the natural resources of the Great Smoky Mountains National Park as incorporated in the park's Natural Resources Database. Streams and watersheds are described and illustrated using a geographic information system (GIS) . Streams were digitized from U.S. Geological Survey 7.5 minute topographic quadrangle maps. Watersheds comprising at least 5 km 2 were delimited on the maps and also digitized into the GIS. Data on elevation and aspect were derived from the USGS 1 : 250000-scale Digital Elevation Model for Knoxville and summarized by watershed. The data were analyzed in terms of stream lengths, watershed areas, drainage densities, predominant aspect, and related statistics. Results are presented in tables, figures, and maps for the entire park, the North Carolina and Tennessee sides, and for the 45 watersheds. Those streams not included in a 5 km 2 watershed are treated in separate pages of tables, figures and maps.
