Description:
The International Ground Water Modeling Center has established a Groundwater Research Data Center that provides information on datasets resulting from publicly funded field experiments and related bench studies in soil and groundwater pollution and distributes datasets for testing and validation of models for flow and contaminant transport in the subsurface. To fulfill its advisory role, the Data Center analyzes information and documentation resulting from field and laboratory experiments in the saturated and unsaturated zones and evaluates the appropriate datasets for their suitability in model testing and validation. To assure consistency in the analysis and description of these datasets and to provide an efficient way to search, retrieve, and report information on these datasets, the Center has developed a computerized data directory, SATURN, programmed independently from any proprietary software. As secondary users of such data are highly interested in information about the assessment of data quality, a primary concern of the Center is the evaluation and documentation of the level of quality assurance applied during data acquisition, data handling, and data storage. In addition to providing referral services, the Data Center distributes on an "as-is" basis, selected, high-quality datasets described in the data directory. The datasets of concern represent differ- ent hydrological, geological, and geographic-climatic settings, pollu- tant compositions, and degrees of contamination.
