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

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 Margarita watershed, San Diego

7. HydroViewer Provides Access to…
Neuse Watershed Collection

11. Hydrologic Data Model We need to represent the physical environment
Hydrologic Fluxes and Flows
Digital Watershed (Atmospheric, surface and subsurface water)
We need to represent the physical environment
and water flowing through it

12. Created first for the Neuse basin
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

16. A 3-D Volume Model of the Beaufort Aquifer
Beaufort confining layer
Beaufort aquifer
Given this information, we want to interpolate the observation data to generate new representations of the subsurface. We want to create cross sections and fence diagrams and to be able to create solid models of the subsurface.
These examples show how fence diagrams and solids can be generated by connecting observations.
We generate these objects to help us describe and reason about the structure of the subsurface.
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
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

25. Education:GIS for Water Resources
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
Notes:
Industrial partners: ESRI, Danish Hydraulic Institute, Camp,Dresser and McKee, Dodson and Associates
Government partners:
Federal: EPA, USGS, Corps of Engineers (Hydrologic Engineering Center)
State: Texas Natural Resource Conservation Commission, Texas Water Development Board
Local: Lower Colorado River Authority, City of Austin, Dept of Watershed Protection
Academic Partners: University of Texas, Brigham Young University, Utah State University

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
