AB: The Hydrologic Information System component of CUAHSI focuses on building a hydrologic information system to support the advancement of hydrologic science. This system is intended to help with rapidly acquiring diverse geospatial and temporal hydrologic datasets, integrating them into a hydrologic data model or framework describing a region, and supporting analysis, modeling and visualization of the movement of water and the transport of constituents through that region. In addition, the system will feature interfaces for advanced technologies like knowledge discovery in databases (KDD) and also provide a comprehensive metadata description including a hydrologic ontology (HOW) for integration with the Semantic Web. The prototype region is the Neuse river basin in North Carolina. A "digital watershed" is to be built for this basin to help formulate and test the hydrologic data model at a range of spatial scales, from the scale of the whole basin down to the scale of individual experimental sites. This data model will be further developed and refined as additional hydrologic observatories are selected by CUAHSI. This will result in a consistent means for the characterization and comparison of processes in different geographic regions of the nation using a common data framework. The HIS will also provide a generalized digital library capability to manage collections of thematically-organized data from primary sources as well as derived analytical results in the form of data publications. The HIS will be designed from the beginning as an open federation of observatory-based collections that are interoperable with other data and digital library systems. The CUAHSI Hydrologic Information System project involves collaboration among several CUAHSI member institutions, with the San Diego Supercomputer Center serving as the technology partner to facilitate the development of a prototype system.
