Abstract
Watershed Delineation Using the National Elevation Dataset and Semi-Automated TechniquesTrack: Water Resources
Author(s): Jay Kost, Glenn Kelly
Federal, state, and local agencies have realized that currently available hydrologic units are not of sufficient scale for many applications. An interagency effort is currently under way to subdivide the existing hydrologic units into smaller units called watersheds and subwatersheds. The National Elevation Dataset contains the best available elevation data merged into a seamless database for the entire United States. This digital elevation data can be readily utilized to delineate watershed and subwatershed basins. This paper describes recently developed ArcView tools designed to facilitate the semiautomatic delineation of watersheds and subwatersheds.
