Second Issue of International Journal of Geoengineering Case Histories [Official This Time]

February 19, 2008 rockman Comments Off on Second Issue of International Journal of Geoengineering Case Histories [Official This Time]

The International Journal of Geoengineering Case Histories has formally announced their second issue. Apparently when I posted about it previously, they had only two of the four papers.

This second issue contains four case histories that come with additional downloads. In particular, check out Dr. Edmund Medley’s Paper on the 2006 Hawaii Earthquakes. He has some neat  photos including some in 3-D (more about his 3-D photos).

Series of Articles on Seismic Analysis

February 19, 2008 rockman Comments Off on Series of Articles on Seismic Analysis

I had an earthquake engineering course in my geological engineering undergraduate program, and an excellent teacher, but man, the math gave me fits! Well, apparently my time has finally come to make the effort to understand it again. A retired Canadian geophysicist/engineer is writing a series of articles on seismic analysis.

USDOE Problems With [Not] Storing Nuclear Waste

February 18, 2008 rockman Comments Off on USDOE Problems With [Not] Storing Nuclear Waste

More problems for the US Department of Energy related to the Yucca Mountain Nuclear Waste Repository. The New York Times is reporting that the DOE is already 10 years behind in a commitment made to Power Companies to store their nuclear waste, and according to the DOE, it will likely be at least another 10 years before they are able to begin accepting waste for permanent storage. Who cares you ask? Well, the US has already payed out $342 million in 60 lawsuits filed by utility companies, and that total could reach $11 billion according to government estimates or $35 billion according to industry estimates before Yucca Mountain finaly opens and begins accepting waste.

Ground-Based Stereo Photography in Geoengineering

February 18, 2008 rockman Comments Off on Ground-Based Stereo Photography in Geoengineering

Stereo photography has long been a tool for geoengineers with respect to aerial photos. But many people are not aware that you can use stereo photography with ground based targets to create 3-D photos. I beleive the technical term is terrestrial photogrammetry (useful if you want some technical articles on the subject). [Red/cyan anaglyph by E. Mathieson]

Dr. Edmund Medley of Geosyntec, owner of the Bimrocks website, has a page on the topic of 3-D Photos in Geoengineering at the GeoEngineer.org website.  On it he has several PDF versions of presentations on the topic that have many examples of the applications of this type of thing to geoengineering projects and suggestions for how to implement it.

Furthermore, Dr. Medley extended a gracious offer to mail Red/Cyan anaglyph 3-D glasses to any GeoPrac.net visitors who are interested. Contact him through his Bimrocks website.

Army Corps Looking for 100 Million Cu Yd of Clay

February 12, 2008 rockman Comments Off on Army Corps Looking for 100 Million Cu Yd of Clay

The US Army Corps of Engineers, New Orleans district is looking for an unprecedented 100 Million Cubic Yards of Clay to be used for reconstruction and fortification of levees in the New Orleans area. Once borrow sources are approved by the Corps, they will likely be contracting directly with a USACOE contractor constructing one of the projects associated with New Orleans Hurricane Protection System.  Material specs are USCS classification of CL or CH, <35% sand, PI < 10, organic content < 9%.

Famed Hole In Danger of Collapse

February 11, 2008 rockman Comments Off on Famed Hole In Danger of Collapse

How ironic. Just last night I posted photos and descriptions of 7 Amazing Holes I received as an email forward from a colleague. Today one of them is in the news. The "Big Hole" in Kimberley, South Africa is making city officials nervous. Apparently some new cracks have formed in the pit walls or somewhere, and officials have decided to shut down traffic on Bultfontein Road that passes within 18-m of the pit. Read on for Google Map and more details. (Photo by No One Nels)

Colorado’s I-70 Could Have Boston’s Big Dig Beat

February 11, 2008 rockman Comments Off on Colorado’s I-70 Could Have Boston’s Big Dig Beat

The planning board for transportation improvements along the I-70 corridor in the Denver area of Colorado is pondering some improvements that, if implemented, could rival Boston’s "Big Dig" for cost. A high-speed train is being considered which alone could run $12 billion.

"A high-speed train is really the long-term solution, and . . . part of America’s long-term future is getting people out of single-occupancy vehicles," said Penny, Frisco town manager and head of the I-70 Coalition. He added that an I-70 project could outstrip Boston’s $14.8 billion "Big Dig."

Seattle Light-Rail Tunnel Likely to Break Ground This Year

February 11, 2008 rockman Comments Off on Seattle Light-Rail Tunnel Likely to Break Ground This Year

Thanks to approximately $100 million from President Bush’s proposed 2009 budget, the $1.8 billion project creating a light-rail line from downtown Seattle to the University of Washington is likely to break ground some time this year. The project will involve twin bored tunnels on the order of 3 miles in length. It is scheduled to open for use in 2016.

There is another notable tunnel project associated with the Seattle Light Rail, known as the Beacon Hill tunnel which I have blogged about before.

Utah Poised to Adopt Geologic Hazard Ordinances

February 11, 2008 rockman Comments Off on Utah Poised to Adopt Geologic Hazard Ordinances

As I’ve reported previously, the State of Utah is in the process of adopting ordinances regulating the development of land that is susceptible to landslides and other geologic hazards. A new bill has been introduced in the Utah House that would give developers a recourse for appeal if they don’t like the decision of a local jurisdiction. More at the Salt Lake Tribune.
