When Robert Koerner and Joe Welsh put together the first hard-bound book on geosynthetics (Construction and Geotechnical Engineering Using Synthetic Fabrics, 1980), neither could truly known the impact this materials sector would have on all of civil, geotechnical and environmental engineering. After witnessing (and contributing to) 30 years of dynamic practice, fascinating designs and product innovation in the geosynthetics field, Dr. Robert Koerner looks back at that first book, which he and Joe began compiling after a chance encounter with a publisher in the late 1970s.

I-CORP INTERNATIONAL's Ian Peggs served as an instructor at the 12th TRI-CORP Liner Integrity Survey and Assessment (LISA) course at the TRI/Environmental campus 23-24 March 2009. He reports that 12 attendees, including one from Chile, took part. The two-day event featured a classroom day and a hands-on, field training day with three test cells on site. Interested attended can then go for the next phase of certification, which involves a one-day field audit during a production geoelectric survey followed by a 90 minute written test. The next course will probably be scheduled for the Fall of 2009. Note: the course can be taken on the road: it has been presented in Albany, NY, at GSE in Houston, and in the Philippines. Read more.

The Indian government is making a couple of moves to improve its nation's aquaculture industry by compelling better practice. Shrimp farms have until April 1 to register officially with the Coastal Aquaculture Authority (CAA) or they will not be eligible to export their goods. Also, shrimp farmers will be required to submit antibiotic-free certification from the ELISA labs approved by the Marine Products Export Development Authority. MPEDA reports that less than half of the 17,000 shrimp farms have registered with the CAA. Learn more here.;

China is the top contributor to the global aquaculture production accounting for 67% (34.4 million tons) of the global production. India is a distant second with just 6% of the global production, followed by Thailand and Vietnam with 3.2% each and Indonesia with 2.5%. Learn more here.;

New Orleans' Gentilly Landfill operated from the 1960s into the 1980s but was closed as environmental concerns and new engineering methods--including the increasing use of geosynthetic containment systems--came about. But the landfill, which is along a canal wall, has been in use again since 2006. It was reopened as a construction and demolition debris landfill after Hurricane Katrina. Now, some fear that the increasing weight of the landfill may weaken the soils around the levee wall and lead to failure of the levee during a storm event. Learn more here.;

Saudi Arabian investors are reportedly planning to pump large sums into developing aquaculture projects not only in the region, but in depressed areas of Asia and Africa. The Saudi-based National Prawn Company (NPC) intends an initial investment of USD 300 million (Dh1.1 billion) to start large-scale fish production in Saudi Arabia and other Gulf countries, says the latest edition of Hatchery International….

It's not often that someone responds to criticism of landfilll proposals (in newspapers) with actual civil engineering information. In the area of Grand Forks, North Dakota, that has happened. Dr. Harvey Gullicks, an associate professor of civil engineering at the University of North Dakota, has waded into the fray to explain why the placement of garbage in a landfill is not, as previously published in the paper, like pushing a sharp object into a thin, home garbage bag. Gullicks note is appreciated by the engineering community--though, to judge by one of the vituperative responses, not by landfill critics in Grand Forks.
