• Part of NSF Cyberinfrastructure program
• Special emphasis on environmental sciences fostered by Margaret Leinen (Asst Dir for GeoSciences)
• CUAHSI Hydrologic Information Systems is one of several pilot projects

Digital Watershed
Hydrologic Data Model
Hydrologic Fluxes and Flows
Digital Watershed(Atmospheric, surface and subsurface water)
We need to represent the physical environment and water flowing through it
Created first for the Neuse basin
Digital Watershed:An implementation of the CUAHSI Hydrologic Data
Model for a particular region
Arc Hydro: Geodatabase model for water resources
• Customization of ArcGIS for water resources.
• Public domain data model and toolset
• Stores time series as well as geospatial data
• Attach remote sensing and climate model files using links
• Integrate data into a coherent space-time framework
ArcIMS Web Server displaying data compiled in Neuse HO Planning Study

Unidata: Atmospheric SciencePrecipitable water in the atmosphere
Cross-section of relative humidity
Images created using Unidata’s Integrated Data Viewer (IDV)
Wind vectors and wind speed (shading)
Unidata delivers real-time weather data including Nexrad to more than 100 universities

Conclusions• A good start has been made with HIS
• Digital Hydrologic Library and Digital Watershed ideas are reasonably well formulated
• Work on mass balances, fluxes and flows is developing
• CUAHSI HIS Symposium in Austin, Tx, on March 7-9, 2005
