Title: State and Regional Hydrologic Information Systems
Abstract: The CUAHSI Hydrologic Information System enables water data to be delivered through the internet in a common language called WaterML, which describes time series of observations measured at a point locations for quantities such as streamflow, water quality, climate and groundwater conditions. Collections of water observations data from a variety of sources are stored in the CUAHSI Observations Data Model and published in WaterML as CUAHSI water data web services. Comparable CUAHSI water data services in WaterML from national water data agencies such as the USGS, are provided through customized interfaces to agency databases. This seminar presents two models for building state and regional hydrologic information systems. The INRA Constellation of Experimental Watersheds (ICEWATER) Information System integrates the data holdings from experimental watersheds across the Intermountain NorthWest Research Alliance (INRA) Universities in Utah, Montana, Idaho, and Alaska. The Texas Hydrologic Information System supplements CUAHSI's national and academic data sources with water data services from state and local water agencies and programs. The National Institutes for Water Resources may be an appropriate organization to work with the CUAHSI Hydrologic Information System (HIS) team to build hydrologic information systems for states and regions of the nation.
