Abstract
Delineation of Drainage Basins for Stream Gauges using the NHDPlus Track: Water Resources Author(s): Tana Haluska, Alan Rea NHDPlus is a suite of geospatial products that build on and extend the capabilities of the National Hydrography Dataset (NHD) by integrating the NHD with the National Elevation Dataset and the Watershed Boundary Dataset (where it exists). Using a combination of raster- and vector-based processing techniques, the NHDPlus datasets may be used to delineate basins for stream gauges in an efficient, automated fashion. In support of a flood data analysis, drainage basins and basin characteristics for large numbers of stream gauges are being developed using the NHDPlus data.
