Water Resource Database (WRDB)

Published Feb. 14, 2013

Description and Background

The Water Resources Data Base (WRDB) is produced and maintained by the Army Geospatial Center’s (AGC’s) Hydrologic Analysis Team. The WRDB provides information on quality, quantity, and availability of water resources in areas of the world of interest to the Department Of Defense (DoD). AGC’s water resource layers are the primary data set populating the WRDB Geographic Information System (GIS); these are keyed to 1:250,000-scale Joint Operations Graphics maps and depict Existing Water Facilities, Surface Water supplies, and Ground Water resources. Coverage is global in extent but focused on arid and semi-arid regions of CENTCOM, EUCOM, and AFRICOM.

Key Capabilities

The WRDB is an improved, expanded and automated water resources intelligence database that can assist commanders in making water support logistics decisions. A Water Consumption Calculator is provided that allows rapid calculation of daily water supply requirements based on the Potable Water Planning Guide. Country and regional scale Surface and Ground Water Analysis products are available in PDF and GeoPDF formats. The WRDB "Water In the News" web service collects and geospatially disseminates global and water resource related news, and can be accessed through the WRDB web portal on SIPRNET. The commercial off-the-shelf GIS software used for the WRDB is ESRI’s ArcGIS.

WRDB Personal Geodatabase and KML: Water resources information is grouped together by Area of Responsibility (AOR) into Personal Geodatabases. The Personal Geodatabases are available for the AFRICOM, CENTCOM and PACOM areas and can be downloaded from our web site. The WRDB is also available in a Google Earth Downloadable Version (KML). Water resource studies in GeoPDF format, at province and country scales, ArcGIS shapefiles and map documents, a free download of ArcExplorer to enable viewing of GIS data without ArcGIS Desktop, GeoPDF hydrogeologic and geologic maps, well logs, imagery, and other available water resources information are also available.

WRDB Urban Water Graphics: Urban Water Graphics (UWGs) are tactical scale insets of the WRDB that provide the warfighter with an entirely new capability to assist in the planning and visualization of military operations in the world's urban areas, in easy to use PDF and GeoPDF format. For example, UWGs may assist the planning and execution of MOUT (Military Operations on Urban Terrain), SASO (Support and Stabilization Operations), threat assessment, and OOTW (Operations Other Than War). The UWG focuses on significant OCONUS cities of interest that have been analyzed as part of the WRDB. The data set contains an overview city base image and margin information, images of key water features, textual descriptions of the surface and ground water resources of the city, and other support information as available

WRDB Country Summaries: Water resource information is also provided at a country or regional scale as a Water Resources Areal Appraisal or Water Resource Assessment, or as part of the Military Capabilities Study or Terrain Analysis Engineering Review. This format often is more suitable for non-arid areas and for strategic planning purposes than the level of detail provided in the standard WRDB output. Most of these studies are available on line.

WRDB Information Requests: Surface water, ground water, and water facility information can be provided to users via a variety of methods (on line, hard copy, CD, external hard drive, etc.) to meet customer requirements. Target or Area Site Analysis evaluations are available upon request. Special WRDB analyses, reports, and coverages can be provided or posted to the Intelinks upon request.

Product Development

Producer - U.S. Army Corps of Engineers, Army Geospatial Center, Warfighter Geospatial Support & Production Directorate. In addition to data being available in shapefile format, some water resource products are available in GeoPDF and KML/KMZ formats. The newest versions of WRDB datasets are built with Arc Geodatabases utilizing NGA Feature Attribute Coding Catalogue structure for portability. Future development will enable users to access all WRDB datasets via a common geodatabase access point (e.g. AGE-GeoGlobe and/or on ArcGIS Server).

Current Status

More than 1,500 Joint Operations Graphics cells (1:250,000-scale) have been digitized into the WRDB GIS. Thousands of features have been digitized at a one-meter resolution scale, as well. Country or regional water studies for nearly 50 countries are available on AGC’s SIPRNET (http://www.agc.army.smil.mil) and JWICS  (http://www.agc.ic.gov) websites under "Products Available/Water Resources". An FOUO subset of the WRDB is hosted on the AGC NIPRNET with PKI security (https://cac.agc.army.mil/). HyDRO (Hydrologic Data Repository for Operations) is AGC’s water resource web mapping page on all of these sites. Water resource information is "mined" or extracted from numerous sources and integrated into the WRDB weekly, significantly expanding the extent of available data. Sources of global precipitation, water chemical analyses, water statistics, and discharge data have been added, along with links to GeoPDF geologic and hydrogeologic maps for most countries. HyDRO is based on ESRI’s Enterprise GeoDatabase (ArcSDE) technology, which allows for rapid retrieval and updating of data so that water resources information received from the field can be added to the database.
