Abstract

The Watershed Boundary Dataset: A National Hydrologic Framework Layer
Track: National Mapping
Authors: Drew Decker, Susan Buto

The Watershed Boundary Dataset (WBD) is a nationally seamless and hierarchical hydrologic unit boundary dataset based on topographic and hydrologic features across the United States. This presentation provides an overview of efforts to integrate WBD with High Resolution National Hydrography Dataset Plus (NHDPlus HR) catchments to create a seamless national hydrologic framework composed of WBD, NHD, and NHDPlus HR.
