  1. CUAHSI Hydrologic Information Systems

  2. CUAHSI Hydrologic Information System (HIS) Project • CUAHSI Standing Committee on HIS functioned from Fall 2001 to Fall 2003 and guided the proposal development • NSF Project was awarded on April 1, 2004 • This a 2-year project to define the requirements for a Center for Hydrologic Information (CHI) and to develop a prototype HIS • Plan for years 3 and onwards is that NSF will hold competitions for: • Center for Hydrologic Information • HydroInformatics Thematic Centers

  3. Project co-PI Collaborator HIS Project Team Upmanu Lall David Tarboton Michael Piasecki Praveen Kumar Xu Liang Jon Duncan LeRoy Poff Yao Liang Ken Reckhow Venkat Lakshmi Chunmiao Zheng John Helly David Maidment

  4. 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

  5. HIS Data Organization Hydrologic Fluxes and Flows Digital Watershed(Atmospheric, surface and subsurface water) Hydrologic Digital Library Digital files of hydrologic information in any form (ADOs), indexed by a metadata catalog (.MIF) Arbitrary Digital Object (ADO)

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

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

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

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

  11. 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

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

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

  14. 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

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

  16. A 3-D Volume Model of the Beaufort Aquifer Beaufort confining layer Beaufort aquifer Built by Gil Strassberg from borehole information collected by the Neuse basin case study team

  17. Groundwater Model of Savannah River Site Radioactive burial ground General head boundaries Package Streams

  18. GIS representation of the horizontal dimension 3000 m 1600 m Each cell is 100 meters by 100 meters

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

  20. What is a Modelshed? A volumetric spatial model registered in three dimensions by a GIS, with which time-varying data, model fluxes, spatial relationships and descriptive metadata are associated Praveen Kumar, University of Illinois

  21. Applications: Helping Remote Sensing and GIS data Talk Time series of Normalized Difference Vegetation Index (NDVI)

  22. Applications: Illinois River Basin Database (ILRDB)

  23. Water Balance in Illinois River Basin Atmospheric moisture flux Monthly streamflow NDVI Climate model precipitation Ratio to the Annual Mean Month

  24. Nov 1 Feb 1 May 1 HIS Info for HO Proposals Now Interact with HO Proposers to clarify data requirements Draft HIS White Paper Review by HIS Users Committee Revision HO announcment is made by NSF HIS White Paper published by CUAHSI HO Proposals are submitted HIS White Paper will define what centralized services the HOs should expect to be provided to them

  25. Graduate course taught jointly between Univ. of Texas and Utah State Univ. All lectures in video streaming format and supporting class materials are archived and available free of charge on internet Class starts this Thursday Grad hydrology class taught similarly next Spring An Arc Hydro book available here for each HO team Education:GIS for Water Resources

  26. 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 • We want to support you in making your HO proposals to the extent we can David Maidment: maidment@mail.utexas.edu John Helly hellyj@ucsd.edu http://cuahsi.sdsc.edu
