Review the scientific literature that I will make available to you on the site geology to answer the following questions and any others that seem pertinent to you:
a. What is the geological history of the Ohio River, and how does this history explain why the Ohio River gorge is so deep? (See Ohio Pleistocene History and Ray, 1974)
b. What are the various geological units (formations) at the site, and which is the dam founded on? Which units will need to support the foundations and abutments of the dam?
c. What are the chief engineering properties and concerns (if any) related to the geological units and geomorphology (i.e., shape of the Earth’s surface) in the vicinity of the dam site?
d. Visit the Ohioseis network web site and review historical earthquake epicenters in Ohio and Kentucky, and study the fault map of Ohio (included in the attached Google Earth kmz file). Is there any history or risk of seismicity in the area? (The next assignment will focus on evaluating the potential risk from induced seismicity related to proposed fracking and/or waste water injection wells in this part of the Ohio Valley.
3) You should also include a References Cited section. You should add to this section each week as we progress through the site investigation project. I have gotten you started with one web resource citation and one print reference. Note that every reference you place in the References Cited section should also be cited in the main text and/or a figure caption. In general, you can cite web pages with the name of the web site and a hyperlink to the cite. You cite traditional references with the surname(s) of the author(s) or the authoring agencies and the date of publication — for example, (McGrew, 1990).
