1. Hydrologic Information System User Assessment Introduction and Highlights

2. Motivation Understand “what is happening now with hydrologic information” at selected universities Obtain “profiles” of user perspectives at selected universities on the needs and priorities for HIS development Provide useful feedbacks to the HIS project development team

3. Approach Questionnaire was posted on the web and distributed to relevant people Focused survey was completed at Utah State, UC-Berkeley, Virginia Tech, and U of Alabama (4 “profiles”) On-site survey was conducted among symposium participants

4. Highlights of Four Profiles Windows is the dominant operating system for users of hydrologic information  75 to 100% of respondents use Windows only or in combination with other OS Excel, GIS, and programming languages (Matlab, C/C++, Fortran, Java, VB) are most widely software Visualization of spatial and temporal data considered one of the highest priority to include in HIS USGS cited as the most widely used data source and data provider

5. Highlights of Four Profiles (cont.) Consensus essential roles for CUAHSI HIS –Retrieval of relevant National, Community, and Hydrologic Observatory datasets –Uploading, archival and sharing of hydrologic data with collaborators and the CUAHSI community Opinions vary considerably on the importance of following roles for CUAHSI HIS –Software system for hydrologic analysis and modeling –Sharing of models, software and hydrologic simulation systems

6. What’s Next Chunmiao Zheng –summary of the U of Alabama profile Xu Liang –summary of the UC-Berkeley profile Yao Liang –summary of the Virginia Tech profile Dave Tarboton –summary of the Utah State profile –results of symposium participant survey LeRoy Poff –hydrologic information needs for aquatic ecology
