The 2013 Geo-Congress from ASCE's Geo-Institute be held 3-7 March 2013 in San Diego, California. The broad theme of the 2013 Geo-Congress has been announced as the "Stability and Performance of Slopes and Embankments," a theme that encompasses all aspects of the geo-profession--and one that certainly utilizes geosynthetics. Learn more about the conference and submit your abstract by 17 April 2012. Learn more here.;
TRI Environmental's John Allen, P.E. will lead a half-day short course on "Slope Stability and Interface Friction Using Geosynthetics" during GeoAmericas 2016 in Miami. Allen has announced the addition...
In a blog posted at Daily Tech, Jason Mick writes on how Dr. Anke Nellesen and colleagues at the Fraunhofer Institute for Environmental, Safety and Energy Technology in Germany created an elastomeric material capable of responding to stresses with something of a "self-healing" property. While the process cannot be totally self-controlled--it requires external monitoring and input of ions--it does seems possible to automate it. Perhaps discoveries like this will lead to polymeric olefin and synthetic rubber membranes that can respond to stress before cracking and failure. Learn more here.;
Pierre Pomerleau, Eng., MBA, President and Chief Executive Officer of Pomerleau Inc., will speak on promising applications for textiles at Expo Hightex on Wednesday, 7 October 2009, at the Bonsecours Market in Montréal. Since he became president of Pomerleau and Beaubois, respectively major construction and architectural carpentry firms, the group's growth has been reflected in an increase in sales, from CDN $200 million to nearly CDN $800 million. This business leader sees Canadian textiles playing increasingly important role in construction projects.
The Global Waste Management Symposium (GWMS) 2010 is taking place at the JW Marriott San Antonio Hill Country Resort and Spa in San Antonio, Texas through October 6. Geosynthetica's Elizabeth Peggs is there. The GWMS is an esteemed forum for the presentation of peer-reviewed applied and fundamental research and case studies on waste management. The bienniel event features significant international participation. This unique educational opportunity will not be around again until 2012. On-site registration is still available.

ASTM International has been selected to provide certification for the U.S. Department of Agriculture biobased labeling program, a voluntary initiative to identify biobased products and to promote their sale among consumers seeking to purchase goods using renewable resources. As the selected provider, ASTM International will manage the Certification Program for Biobased Products, which will determine the product and package biobased content for manufacturers and vendors that choose to participate.
In Florida, a higher tax will be placed on phosphate companies to encourage quicker closure of former gypsum operations. Florida has a long successful gypsum mining industry, but its environmental legacy is not nearly as admirable. Significant cleanup and capping are required for operations dating back decades. The Ledger article includes an interesting close-up photo of a geomembrane being seamed. Learn more here.;

The Kennewick Irrigation District (KID) in Washington State has had a number of seepage issues in its earthen canals this year. The Badger East Canal is currently experiencing significant seepage problems. While the earthen canals are designed for it, the Badger East Canal had a geosynthetic liner for water conservation between 1989 and the middle of this year. Rather than replace the liner, which KID felt had reached the end of its service life, the canal was deepened and packed with a bit of clay. The result has been flooded basements and a need to reapproach the canal's management. Learn more here.;

The Journal of Environmental Quality's (JEQ) most recent issue includes "Can Urban Tree Roots Improve Infiltration through Compacted Subsoils for Stormwater Management?" The researchers who produced the article examined the effects of root penetrations on water infiltration and examined water detention system using special soil arrangements and geotextile separation fabrics. “Manipulating root penetration through these separation geotextiles could potentially play a large role in bioretention system function and design," says the project lead, Susan Day of Virginia Tech.

On Monday, March 14, during the Geo-Frontiers 2011 conference (13-16 March 2011, Dallas), John Lostumbo of TenCate Geosynthetics will present a much-anticipated paper on "Geosynthetic Enabled with Fiber Optic Sensors for MSE Bridge Abutment Supporting Shallow Bridge Foundations." Geotextiles with fiberoptic components provide a resource for monitoring various design functions including strain. Data collected from fiber optic monitoring can be used to determine the functional longevity of civil structures helping to insure safety as well as providing data which may be used for evaluation of design methods.

The International Geosynthetics Society's (IGS) Indian Chapter (IGS India) has moved forward on its initiative to publish the Indian Journal of Geosynthetics and Ground Improvement on a twice-yearly basis, with the first issue covering January-June and the second issue July-December. Read about the articles in and download the inaugural issue here in PDF, learn about the publication's mission, and download guidelines to help you submit material to the journal.
The newly constructed Arkun Dam hydropower facility on the Çoruh River (Turkey) would have been considerably more expensive if conventional concrete walls were used along the edges of the power station. NAUE Geosynthetics profiles the project and the reinforced earth option that was selected and which saved 40% on the cost for this portion of the project.
The Winter 2007 edition of the International Association of Geosynthetic Installers (IAGI) newsletter is available.

Engineers investigating the raw water reservoir in Fremont, Ohio have discovered some karst. Among other effects, karst can cause seepage, piping, and instability. The engineers' report from Arcadis recommend a composite liner system (HDPE or LLDPE geomembrane and GCL) across the entire slope, protected by geotextile and cover soil, and geogrid reinforcement. The city has roughly one year to complete the reservoir project and must now seek approval to alter the design and include a lining system. Learn more here.;
