1999 UZIG Meeting at the USGS Menlo Park Offices, January 13-15, 1999
A record number of people (69!) attended the 1999 Unsaturated Zone Interest Group (UZIG) Meeting at the USGS Western Regional Center, Building 3, in Menlo Park, CA. Attendees, who included personnel from Water Resources and Geologic Divisions of the USGS as well as USDA-ARS, DOE, Pacific Northwest National Lab (PNNL), Lawrence Berkeley National Lab (LBNL), Lawrence Livermore National Lab (LLNL), the USDA Salinity Lab (USSL), and the Army Cold Regions Reseach Lab (CRREL) were treated to two days of enlightening seminars and lively discussion on January 13 and 14. A half-day field trip to the Santa Clara Valley Water District recharge ponds took place on January 15. Welcoming addresses were presented by Andrea Alpine, Acting Regional Director, USGS, WR; Peter Anttila, Assistant Regional Hydrologist, USGS-WRD, WR; and Steve Ingebritsen, Chief, Branch of Regional Research, USGS-WRD, WR. Scientific presentations were organized into six sessions. Session I addressed investigations near waste disposal sites and included talks by Lorrie Flint, Alan Flint, Dave Hudson, Dave Stonestrom, and John Nimmo. Phil Meyer of PNNL gave a talk on estimating uncertainty when site-specific data is limited. Session II dealt with hydraulic and transport properties. Rien van Genuchten of USSL made a presentation on hydraulic property characterization and estimation in support of predictive flow/transport modeling. Presentations were also made by Steve Grant of CRREL and Brian Andraski. Session III consisted of tours of USGS Menlo Park labs, poster presentations, and demonstrations of computer software. Session IV was devoted to talks on aquifer recharge. John Risley and Joe Hevesi both made presentations on the use of watershed models to estimate recharge in large basins. Al Rutledge talked about computerized hydrograph separation. Mike Fayer of PNNL and John Izbicki made presentations on studies in arid regions, and Art Baehr discussed work in southern New Jersey. In Session V Ken Hollett discussed recent activities of the USGS Office of Ground Water, and Bill Isherwood of LLNL described DOE's recent Vadose Zone Science Effort. The final session of talks, on liquid, gas, and chemical fluxes in the unsaturated zone, included presentations by Boris Faybishenko of LBNL, Dave Stannard, Hubert Morel-Seytoux, John Rogie, and Mark Reid. The group dinner on Thursday evening at the Su Hong restaurant provided an opportunity to relax and continue discussions. For the next nationwide UZIG meeting, it was agreed to shoot for the fall of 2000 as a target date. Albuquerque is a possible location. Thanks go to John Nimmo, Kim Perkins, Angus Lewis, and crew for efforts in organizing and running the highly successful meeting Thanks also to Peter Martin for arranging the field trip.
