These applications have been developed by NHD users and are listed
here to assist others in applying the NHD. If you are interested in
sharing your NHD application, please contact nhd@usgs.gov.
The following
applications are downloadable from this Web site. Download problems
should be reported to
nhd@usgs.gov.
All other questions should be directed to the application
developer.
- USFS Reprojection Tool - This tool was developed by the U.S.D.A.--Forest Service for the National Hydrography Dataset (NHD) NHDinGEO format, but can function on any personal geodatabase.The USFS Reprojection Toolbar changes geographic projection and can transform datums using all available ESRI ArcObjects algorithms. This is an add-on toolbar written for ESRI's ArcGIS 9.x (ArcCatalog). The advantage is that it reprojects whole personal geodatabases at once, and updates the metadata at both the Geodatabase, Dataset, and Feature class levels in both the Data Quality and Spatial Reference sections of standard FGDC metadata--or creates its own metadata if there is none.
- EventMaker - This software
was developed by the U.S. Forest Service to fill a hole in the
linear referencing tools available in ArcMap, which is the
ability to interactively create a linear event based on endpoints.
The software also creates point events and is available for ArcGIS 8.3 and 9.0.
- NHD
Watershed - This application employs the NHD and other
supporting data layers to delineate a watershed from any point on any
NHD reach.
- NHD
Watershed Characteristics - This application employs the
NHD and other supporting data layers to compute characteristics of
choice for watersheds delineated using NHD Watershed.
- West Fork
Cedar River Demo - This application demonstrates how the NHD
can used to facilitate the integration of water resources information.
The following Web sites describe other NHD applications of interest.
- NHDPlus Offers New Geospatial Data and Tools for Water Quality Managers - Between 1996 and 2000, the Environmental Protection Agency (EPA), the U.S.
Geological Survey (USGS), and other federal, state and local agencies
collaborated to produce the National Hydrography Dataset (NHD), a comprehensive
set of digital geospatial data about surface water features such as
streams, rivers and lakes. These data can be used by water quality
managers to make maps, perform upstream/downstream queries, and link other
water-related information to the NHD network.
In 2006, this interagency collaboration produced NHDPlus, a suite of
application-ready geospatial products that build upon, and extend, the
capabilities of the medium-resolution NHD. NHDPlus integrates the NHD with
the National Elevation Dataset (NED) and the Watershed Boundary Dataset (WBD).
It includes an enhanced NHD stream network with improved names,
value-added attributes (such as stream order), incremental drainage areas
with landscape characteristics, and flow volume and velocity estimates for
pollutant dilution modeling. EPA and USGS have linked many water quality
databases to NHDPlus, including stream gaging stations, water quality
monitoring sites, and impaired waters, enabling these databases to be
queried and analyzed in upstream/downstream order. NHDPlus greatly
enhances the ability of researchers and water quality managers to analyze
and model water quality data. For more information on NHDPlus, visit

- WATERS - Watershed
Assessment, Tracking and Environmental ResultS (WATERS) employs the
NHD as the spatial framework for integrating EPA water program
databases.
- NRIS
Water - The U.S. Forest Service Natural Resource Information
System (NRIS) Water module employs the NHD as its common hydrologic
framework to support aquatic resource decision-making on National
Forests.
- New
England SPARROW - This NHD-based version of the USGS SPARROW
water-quality model aids the development of regional nutrient
water-quality criteria and total maximum daily loads (TMDL) for New
England streams.
- Fish Passage Decision Support System The FPDSS is a web-based application, funded by the U.S. Fish & Wildlife Service, that provides policy makers and the public with information on barriers to fish passage. It uses the NHD for mapping and barrier removal modeling operations.
- Vermont
Flow-Frequency Tool -
The USGS in cooperation with the Vermont
Agency of Transportation developed this NHD-based tool to automate the
calculation of basin characteristics required by flow-frequency
equations that estimate peak-flow frequency and flow duration.
