Organization of Open Source Public Resources

HydroShare is shared web-based infrastructure -- information technology that provides advanced capabilities to conduct hydrologic research.  Initial development of HydroShare was enabled through a grant from the National Science Foundation (NSF), which funds collaboration of federal, institutional, and individual researchers to cooperatively design and build cyber-infrastructure.  The architecture and shared resources like code, maintenance, and support rely on cooperative efforts within which researchers may self-organize their data, models, and publications.  

HydroShare code and development are managed on Github ( with 30 HydroShare related repositories (as of April, 2017) coordinated by NSF Principal Investigators, grant funded researchers and developers, and professionals at the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUASHI) and Renaissance Computing Institute (RENCI).

Institutions supporting the public resource

CUAHSI is a community-governed organization that has a Board of Directors composed of university professors from across the United States. In addition, CUAHSI’s activities are influenced by a number of Standing Committees that recommend policies and priorities to the Board of Directors. The Standing Committee on Informatics provides oversight for all of CUAHSI’s data and modeling activities including HydroShare.  CUAHSI is funded by the National Science Foundation (NSF) as a facility with a cooperative agreement that must be renewed every five years. This funding cycle ensures that CUAHSI has the resources necessary to develop and maintain data services for the science community that are reliable and sustainable.

The HydroShare system is hosted at RENCI in their data center on equipment that was purchased with NSF project funding to support the development of HydroShare.  The system has 50 TB of storage on servers running iRODS - the data management system used. The iRODS Consortium provides support through membership and on contract with partners (including Intel, IBM, Dell and university and computing institutes from around the world). There is an additional 50 TB in an offsite location used for backup and disaster recovery, in case the RENCI facility is compromised.  CUAHSI has budgeted in the short term to contract with RENCI to continue to operate the system.  Long term hosting arrangements are in process.
