Presentation Transcript

  1. CUAHSI Hydrologic Information Systems

  2. Project co-PI Collaborator HIS Project Team Yao Liang John Helly

  3. Environmental Cyberinfrastructure • 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

  4. 1. Hydrologic Observations Database Hydrologic System Sampling Sensing Transmission Recording Laboratory Analysis Transmission Recording Editing Storage Off-Site Measurement On-Site Measurement Retrieval

  5. Sensor Network Interfaces to Digital Library Example is for wireless network in Santa Margaritawatershed, San Diego

  6. HydroViewer Provides Access to… http://cuahsi.sdsc.edu Neuse Watershed Collection Santa Margarita Watershed Collection + your Hydrologic Observatory Data Collection

  7. Individual Samples Hydrologic Metadata Definition Numerical Models Air-Q HSPF MM5 Sensor Arrays NCDC METADATA NWIS NCEP NWS NGDC Data Centers Data Harvesting

  8. 2. Hydrologic Representation Hydrologic Observation Data Geospatial Data (GIS) (Relational database or delimited ascii) Digital Watershed Remote Sensing Data Weather and Climate Data (EOS-HDF) (NetCDF)

  9. 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

  10. Digital Watershed:An implementation of the CUAHSI Hydrologic Data Model for a particular region Created first for the Neuse basin

  11. 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 Arc Hydro: Geodatabase model for water resources

  12. http://neuse.crwr.utexas.edu/ ArcIMS Web Server displaying data compiled in Neuse HO Planning Study

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

  14. Neuse Basin: Coastal aquifer system Section line Beaufort Aquifer * From USGS, Water Resources Data Report of North Carolina for WY 2002

  15. Create a 3 dimensional representation Geovolume Each cell in the 2D representation is transformed into a 3D object Geovolume with model cells

  16. 3.Hydrologic Analysis Statistics and Hypothesis Testing Hydrologic Process Modeling Digital Watershed Visualization Data Mining and Knowledge Discovery

  17. Center for Hydrologic Information Data Flow Applications Data Models Reference Models Data Models Hydrologic Fluxes Digital Watersheds Hydrologic Observatories Data Transformations HOi HOi HOi Hydrologic Synthesis Center HOi HOi HOi Federated Digital Library Data Harvesting Distributed Data Sources Distributed Data Sources Distributed Data Sources Distributed Data Sources Distributed Data Sources Distributed Data Sources Distributed Data Sources Distributed Data Sources

  18. New Concept of Publication Hydrologic Digital Library Normal Method +

  19. 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 David Maidment: maidment@mail.utexas.edu John Helly hellyj@ucsd.edu http://cuahsi.sdsc.edu
