Wednesday, March 5, 2003

Discussion session with EBTAG
8:30-9:00 a.m. Discussion leader - Tien Grauch
Summarize events/talks of previous day
Follow-up on list of "critical issues" developed last year
9:00-11:00 a.m. Break-out groups
3-4 groups will break out for discussion of ways to address/study a specific topic in order to ultimately improve the understanding of ground water in the basin. Each group will have a discussion leader and recorder. We will choose topics/groups at the beginning of this session, using the following list as a starting point:
  • geologic mapping, borehole studies & heterogeneity of aquifers
  • faults & compartmentalization of aquifers
  • subsurface studies & thickness of aquifers, especially under basalt
  • indirect detection of aquifer properties or ground-water flow at depth
  • integration of geology, geophysics, & hydrology
  • geology/geophysics of bedrock areas & estimating recharge
11:00-noon Break-out group reports
Group leaders report the results of the group's discussion to the larger group.

Field trip near the Buckman well field
noon-5:30 p.m. (approx.)

Dan Koning will lead us on a walk up an arroyo to examine different facies of the Santa Fe Group and discuss the heterogeneity of grain size and cementation in relation to permeability. We will cross two faults, where we can examine fault zone properties and discuss the potential effects on ground-water flow. One fault is associated with a spectacular, recent fissure. The walk back will include discussion of the well field. 2-3 miles round trip.

Transportation will be provided; bag lunches will be available for purchase ahead of time.
