Advanced Geophysics Workshop To: "E - All WRD Employees" cc: "Frederick P Haeni, Chief (Hyd), Hartford, CT" Subject: Advanced Geophysics Workshop Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Date: Fri, 17 May 1996 14:56:09 -0400 From: "Frederick P Haeni, Chief (Hyd), Hartford, CT" The Office of Ground Water is organizing an advanced workshop on the "Integrated Uses of Geophysics in Hydrology and Geology". The workshop will bring together ground-water scientists, geophysicists, and geologists fron WRD and GD to discuss advances in geophysics, particularly in relation to resource and site assessment, fractured-rock hydrology, ground-water transport, and geologic mapping. Workshop participants will learn how to use and apply standard and new surface- and borehole-geophysical methods in their project work or research. The workshop is scheduled for the week of November 4, 1996, at the Ramada Inn West (formerly the Holiday Inn) near Golden, Colorado. Participants will mainly be personnel who have had some experience in the application of geophysical methods in their work; however, personnel without that experience may also benefit. The following preliminary agenda is divided into an overview of the whole meeting (Master Plan), and a more detailed agenda with potential topics. By this e-mail message we are soliciting your comments,suggestions, and (especially) volunteers for posters. Please contact one of the following planning-committee members: Pete Haeni (phaeni@usgs.gov), Pat Tucci (ptucci@usgs.gov), John Williams (jhwillia@usgs.gov), Dave Fitterman (fitter@usgs.gov), for general comments and suggestions, or Karl Ellefsen (ellefsen@usgs.gov), to volunteer a poster. This e-mail also serves as a call for PRE-REGISTRATION. This pre-registration doesn't obligate attendance; it's only to give us an estimate for planning purposes. *** Please let us know, via e-mail to: Wayne Lapham (wlapham@usgs.gov), or Byron Stone (bdstone@usgs.gov) by 5/31 if you or others in your office might be able to attend. Keep in mind that Tuesday, November 5, is Election Day. *** Thank you in advance for your comments and speedy response. Pete Haeni Chief, Branch of Geophysical Applications and Support *********** MASTER PLAN: The meeting will consist of three days of indoor activities and one field demonstration day. The three inside days will look something like this: AM - 2 hours of talks on "Introduction, Potential Applications, and Emerging Technologies" of a method or group of methods (4 talks each day). These will be followed by talks on "Integrated Geophysical Method Applications to Hydrologic and Geologic Problems" (3 talks each day). The first part will focus on state-of-the-art and emerging technologies, and how they may be applied to hydrologic and geologic problems, rather than a re-hash of topics covered in Denver training classes. The second part will be presentations (case study) that discuss a problem, and how geophysical methods were used to help solve it. LUNCH PM - "Hands-on" workshops/computer demonstrations on different methods and interpretation techniques. These would be set up similar to those done at the geophysics session at the Advanced Ground Water Workshop (a group working at a computer to manipulate/interpret/visualize a geophysical data set). We envision 4 stations in 3 rooms (separate, theme related topics in each room) each day. People (organized into 3 groups) would choose a room each day, and spend about an hour at each station. EVENINGS: Socializing and discussions, a voluntary poster session, or some additional work on the computers for participants who want to look at something in more detail. Perhaps an organized dinner with a keynote speaker. Day 4 will be a field demonstration day. The participants will split into two groups. One group would visit the borehole demos and one group would visit the surface demonstrations in the morning, then they would switch in the afternoon. - ----------------------------------------------------------------- DRAFT AGENDA MONDAY, NOV. 4 AM: 1.
