  1. Web Access to Long-term Research Hydrology Data Doug Ryan USDA Forest Service Research and Development

  2. The Needs • Watershed scale information • Needed to address many issues • A few examples: • Post-fire risks • Watershed restoration/rehab • Fish passage

  3. Advantages of Research Data • Precisely measured • Quality controlled • Small watersheds • Supporting data available (metadata) • Land use known and/or controlled • Many other aspects studied

  4. Watershed Cross-Comparison Post & Jones (2001)

  5. Long-term Data Exist • Experimental watershed studies • In many parts of country • High quality data • Many variables measured/controlled • But access has been difficult • Needed: One-stop, easy access

  6. Individual Site Central Site Public User Relational Database CGI Script Harvester Solution: HydroDB “Centributed” Mechanics (Baker et al. 2000 BioScience) Monthly Data (V-One,V-Many) CGI Script Dynamic URL Site Database Daily Data Static URL Graphics Local Script Exchange filters Exchange format Report formats Distribution filters

  7. HJ Andrews Experimental ForestV-notch weir

  8. Beta version of web harvester • http://www.fsl.orst.edu/hydrodb/index.htm • Primarily developed for data input • Next phase will improve public access

  9. Coweeta (NC) daily stream discharge

  10. H. J. Andrews (OR) daily Stream discharge

  11. H. J. Andrews (OR) total daily precipitation

  12. Fraser (CO) daily stream discharge 1991

  13. Fraser (CO) daily precipitation 1991

  14. Fraser (CO) mean daily air temperature 1991

  15. HJ Andrews Experimental Forest V-notch weir

  16. Next Goals • Improve user-friendliness • Add tools to use long-term data: • Fish passage • Post fire risk • Roads/culvert design • Add other kinds of observations • Suggestions?

  17. Conclusions • Long-term hydrology important • Web-access now possible • More development needed: • Add more types of observations • Add tools to use this gold mine
