The CUAHSI-HIS project must operate through multiple working partnerships. The CUAHSI-HIS team continues to build partnerships with government agencies that collect or use water data, with industry needed to develop the commercial software to support an operating system, with supercomputer centers that must design and provide needed web services and databases, and with domain sciences from many academic disciplines. It will take these partners and others to build the system. There are many aspects where these relationships will be critical as we integrate the system into the community, and our need include: data partners, development partners and collaborators (partners who test HIS or collaborate in some other way). Many of our partners are listed below, along with descriptions of what we are doing together, sometimes even including source code, to give other members of our community ideas on how they might participate, and other resources that they might be able to incorporate into their work. As many partners as we have listed, we can always use more, so consider joining us.

Data partners


The USGS is collaborating with CUAHSI-HIS to facilitate access to USGS data through WaterOneFlow Web services and to implement its own variations of WaterOneFlow web services for direct access to USGS data.

CUAHSI-HIS is also relying on the NHDPlus data set (developed by USGS and EPA) as a geospatial framework for representing surface water data.


The EPA Office of Water is collaborating with CUAHSI HIS to facilitate access to EPA STORET (STOrage and RETrieval) water quality data through WaterOneFlow web services. Discussions are ongoing to harmonize the EPA Water Quality Exchange (WQX) data exchange framework with WaterML. HIS is also relying on the NHDPlus data set (developed by USGS and EPA) as a geospatial framework for representing surface water data.


NOAA and CUAHSI are collaborating on web services for the National Weather Service Automated Surface Observation System (ASOS) and NCEP reanalysis model output. NCDC has also developed its own web services to its Climate Data Online Datasets based on WaterML.

Oak Ridge National Lab DAYMET

Web services have been established to serve DAYMET model output. DAYMET, developed by the Numerical Terradynamic Simulation Group (NTSG) at the University of Montana generates daily surfaces of climate variables over complex terrain.


Web services have been established to serve NASA Moderate Resolution Imaging Spectrometer (MODIS) data.

Development partners


The partnership with the Environmental Systems Research Institute (ESRI), has resulted in ESRI donating its resources to program the Data Access System for Hydrology (DASH) that is part of the HIS Server.

Australian Commonwealth Scientific and Industrial Research Organization (CSIRO)

CSIRO is developing the Australian Water Resources Observations Network (WRON) [], drawing upon ideas from HIS such as ODM and WaterML web services. WRON has developed the ODM KML gateway that based on ODM web services provides a KML file for visualization of sites in Google Earth.

Arizona State University

The Arizona Hydrologic Information System being developed at Arizona State University is developing a MySQL version of ODM and Java version of web services.

U.C. Berkeley

The Angelo Experimental Watershed is developing cyberinfrastructure based on ODM and Web services using Java and Postgres. The Berkeley water center, in partnership with Microsoft, is exploring Online Analytical Processing (OLAP) cube technology for visualization and analysis of ODM data.

Idaho Experimental Watershed Network

The Idaho Experimental Watershed Network has developed staging procedures for implementation of HIS server functionality (ODM and Web services) in a distributed system involving protected (firewall) networks. Idaho State University is also developing components for using HIS within the Mapwindow open source GIS and for connecting models using OpenMI.


WATERS Network test beds

The 11 WATERS network observatory testbed sites are each pursuing separate science goals as they work with HIS in developing supporting cyberinfrastructure.

University of Iowa and Iowa Institute of Hydraulic Research (IIHR)

HIS is collaborating with the University of Iowa to provide data access and interpretation of Stage II Nexrad rainfall data.


Collaboration involves the use of UNIDATA NetCDF, THREDDS data servers and metadata.


The Geosciences Network (GEON) project is collaborating with HIS on ways to make GEON data, such as high resolution topography data from LIDAR, available to the Hydrology community.


Earthchem has developed data systems for geochemical data. HIS is collaborating with Earthchem on the best ways to harmonize HIS and Earthchem data models.

European Water Framework Harmoni Projects

The Open Model Interface (OpenMI) has been developed as a standard for the linking of time series models. HIS is collaborating with OpenMI on its use in HIS. The HarmoniRiB database system has developed a sophisticated object oriented data model for the storage of watershed information. HIS is collaboration with HarmoniRiB on using aspects of this functionality.


Collaboration involves the use of Microsoft SQL Server and assistance with data system implementation and security.


Kisters, a global company supplying software systems for water sensor data, is collaborating with HIS to look for opportunities to better serve its clients by using HIS technology and standards.

Danish Hydraulics Institute

The Danish Hydraulics Institute, a producer of water modeling software, is collaborating with HIS to look for opportunities to better use HIS data and technology in its software.


The USDA Agricultural Research Service is designing a system for publication of data from its experimental watersheds, called STEWARDS. Discussion is ongoing on collaboration to determine the best means of linking STEWARDS and HIS.

Long Term Ecological Research (LTER) Network

HIS is collaborating with the LTER network on ways to make LTER data available through HIS.

Critical Zone Observatories (CZOs)

HIS is collaborating with CZOs on ways to make CZO data available through HIS.

National Center for Supercomputing Applications (NCSA)

The NCSA environmental cyberinfrastructure demonstration project is exploring ways to use HIS web services in integrated work flow applications.

Texas Advanced Computing Center (TACC)

TACC has compiled in relational database format, a complete history of calibrated Stage III Nexrad radar rainfall data and is working with HIS to provide access to this data.
