Abstract
 Using GIS and Remote Sensing for NPS Identification and Prioritization Track: Water Resources Author(s): John Holcombe III, Donald Malone Using Remote Sensing and GIS techniques are undoubtedly two of the most powerful tools to facilitate water quality improvements in watersheds. During the past twenty years, the Tennessee Valley Authority has been extensively involved in the identification and abatement of land-based non-point source (NPS) environmental problems in various watersheds. GIS databases derived from image analysis are a cost-effective tool that watershed planners can use for developing and implementing NPS pollution corrective actions. This process provides the impetus for bringing agencies, industries, interest groups, and landowners together to work toward a common goal. Information gained from this process helps secure grant funding to improve water quality in a watershed. Furthermore, this database documents the source, location, and magnitude of non-point problems within watersheds. The generated information provides a foundation for fostering environmental awareness, targeting priority-impacted watersheds, and identifying abatement measures.
