Geologic Considerations for the Evaluation of Dams

 
Moderators: Brian Greene, U.S. Army Corps of Engineers, Douglas Boyer, Federal Energy Regulatory Commission, Marie Garsjo, National Resources Conservation Service, and J. David Rogers, University of Missouri – Rolla.
 
Geologic considerations play an important role in the design, construction, and maintenance of dams. This session discussed dam siting and borrow investigations, site investigation techniques, foundation grouting, and construction mapping. At existing dams, performance monitoring investigations, Potential Failure Modes Analysis (PFMA), other safety evaluations, and foundation improvement techniques were discussed. Links to presentations, when available, are listed below.
