October 1, 2012 Sidney B. Garland II, PE, BCEE Restoration Services, Inc. spoke on “Watershed Management as a Basis for Environmental Restoration” (PDH)
In Oak Ridge, Tennessee the Department of Energy and its predecessor agencies have had a mission over the past fifty years of uranium enrichment, weapons production, and energy research. As a result of this mission a legacy of hundreds of contaminated sites remains on the Oak Ridge Reservation. The remediation strategy for these sites is based on watershed management.
October 15, 2012 Isaac A. Jeldes described the results of his research on slope stability.His work shows that slopes of soil or other granular material are more stable if the material is left in a concave shape. He illustrated how concave shapes are found in landforms, such as the shape of a volcano. The availability of GPS control on grading equipment makes it possible to finish slopes to optimum shapes.
October 22, 2012 Dr. Bruce A. Tschantz, P.E. Professor Emeritus – Civil and Environmental Engineering UTK spoke about the safety of low head dams.There are thousands of low head dams in the country and they cause many deaths each year. The danger depends on the flow rate. At low flows and high flows the dams are not dangerous but at a flow rate that results in a hydraulic that recirculates water back toward the dam, the dams are deadly. The water that recirculates is full of bubbles and has a
low density so a person caught in the “boil” sinks and cannot get out of the recirculating water. This is an issue where the Technical Society can help with public awareness and help move

the political processes needed to remove these dams.
Bruce has approximately 40 years as Engineering Consultant and Expert Witness to several
local, regional, and national engineering firms, industries, city/state/federal agencies, citizens groups, private individuals, and attorneys in the areas of: urban drainage; flooding; rehabilitation, design and failure of dams; hydraulic and hydrologic engineering; sediment transport; land erosion; basement and crawl space water problems; and drowning deaths at low-head dams, culverts, etc.
Of particular relevance to the topic he spent three years as Dam Safety Consultant and Advisor to Executive Office of the President, Office of Science and Technology Policy, Washington, D. C. and one year as Chief of Federal Dam Safety Program (on leave from university), Federal Emergency Management Agency (FEMA.), Washington, D. C.

The speaker for the Technical Society of Knoxville meeting on October 29, 2012 was Don
Barger – Regional Director – Southeast Regional Office of the National Parks Conservation Association (NPCA). Don founded NPCA’s Southeast Regional Office in 1992.
He described several problems that he was involved with in which a national park was threatened by inappropriate construction or development. He described the negotiations that went into the road to nowhere on the shores of Fontana Lake. He told how a joint petition by NPCA and the City of Middlesboro, KY resulted in protection of the Fern Lake watershed adjacent to Cumberland Gap NHP. The lake was saved from a disasterous coal mine.
Before joining NPCA, Don worked as a community organizer for Save Our Cumberland Mountains and directed the Citizens Mining Project for the Environmental Policy Institute/Friends of the Earth.
