Symposia
Symposium #1:
TUNNELING
Convener and Moderator: Alan Howard,
Brierley Associates, LLC
Wednesday, September 17, 2008 ~ Afternoon
Technical Session #1
Room: Maurepas
Successful tunneling projects begin with meaningful input from engineering geologists starting early during the planning stages. An early understanding of geologic conditions is needed to adequately perform route selection and screening. As routes are selected and refined based on technical, social and economic factors, focused geotechnical investigations conducted by skilled geologists and engineers are needed for design and the preparation of suitable contract documents for bidding or design-build procurement. Most tunnels in the United States in recent years require the development of a Geotechnical Baseline Report (GBR). The GBR constitutes a single geotechnical interpretive report to be included as part of the contract documents with the purpose of being the sole repository of contractual statements about subsurface conditions and behavior anticipated during construction. Getting it right each step of the way means all the difference to all parties concerned between a successful project and a potentially disastrous dispute.

Symposium #2:
COASTAL GEOLOGIC
HAZARDS AND PROTECTION
Conveners and Moderators: Burton Kemp, Kemp Associates, Inc. and Michael Culp
Thursday, September 18, 2008 ~ 3/4 Day
Technical Sessions #5 and #9
Room: Maurepas
As one of the Nation’s largest wetland repositories, the Louisiana Coastal Zone is a vital contributor to the Nation’s economy and seafood industry. Unfortunately, these Louisiana coastal wetlands are suffering from the greatest loss of wetlands, equal to the size of a football field each year. While much of the loss is due to man’s activities in the coastal zone, naturally occurring geologic hazards contribute significantly to this loss. Subsidence, shoreline erosion, faults, and sea level rise, are all contributors to the demise of Louisiana’s Coastal marshes and wetlands. We have invited a number of distinguished Coastal Scientists to address the Geologic Hazards inherent in Coastal Zone and some of the protective innovations available for consideration.

Symposium #3:
SEISMIC SOURCES IN THE
CENTRAL U.S.:
IS NEW MADRID ALL THERE IS?
Conveners and Moderators: Greg Hempen, URS Corporation, and Eugene “Buddy” Schweig, USGS
Thursday, September 18, 2008 ~ 3/4 Day
Technical Sessions #7 and #11
Room: Conde/Frontenac
The state of practice for evaluating seismic hazards may be in flux concerning sources other that the New Madrid Seismic Zone. Certainly the most significant threat is from the New Madrid Zone. Many practitioners evaluate other zones about the New Madrid as background seismicity. A decade ago many may have used specific seismic source areas with “floating” events.
The Seismic Sources in the Central U.S. Symposium offers to discuss whether general background seismicity remains the best model outside of the New Madrid Seismic Zone. Has the science developed adequately to revise the practice or does background seismicity address the issue most properly? Many feel that the Wabash Valley Seismic Zone should be recognized. Other zones also have been recommended in the past.
