WEDNESDAY, SEPTEMBER 22 – AFTERNOON Technical Session #1A Coastal Hazards Symposium

(Sponsored by AEG Carolinas Chapter)

We know that Sea Level is rising. In some cases, Sea Level is rising at greater rates than predicted. As Geoscientists and Engineers, how are we involved? Over the coming years we will deal with these issues through an interaction of Scientists, Engineers, Planners, Educators, and the Public. The following presentations are just an initial sampling of many that will follow. AEG hopes to have more Coastal Hazard Symposia over the next few years, dealing with all coasts, and international impacts, and Coastal Hazards and Sea Level Resiliency will be a focus of the Annual Meeting in Philadelphia in 2024. However, this year we start with three presentations involving the US Gulf Coast.

Technical Session #2 Tunneling Symposium

(Sponsored by McMillen Jacobs Associates)

Continuing our tunnel symposium series of “Standing on the Shoulders of Giants,” we dedicate this session to the late Dr. Ron Heuer who was slated to be this year’s keynote speaker. Our session will include a variety of topics regarding the impact of Engineering Geology on tunneling projects as well as case histories of such projects. Talks discuss tunneling in a wide variety of locations across the United States, methods for mapping, imaging, modeling, and assessment of ground and groundwater conditions and inflow. Several specific tunnel projects will also be discussed.
