California Levees Need $500 Million
08/31/2010
Many levees in California are in need of repair, according to experts. Gov. Arnold Schwarzenegger pledged $500 million to upgrade the state's levee system, but the Army Corps of Engineers -- which is busy in Afghanistan -- is needed to fix most of the levees, an official said. Without repairs, a levee failure in the Sacramento area could hamper the ability of 25 million Californians to secure fresh water, experts noted. ID:

Lothar Bestmann, Inventor of Sustainable Waterways Construction Measures, Turns 80
08/27/2010
Mr. Bestmann, a Hydraulic Engineer with a green thumb, is recognized for pioneering the use of synthetic geotextiles on major marine construction applications in the 1960s, as well as his later inventions of numerous methods for addressing construction, habitat, and water quality on waterways, including specialized use of biodegradable materials to aid plant establishment. In addition to holding patents for many innovations such as floating breakwaters, artificial habitat islands, revegetation modules, and nutrient removal systems, Mr. Bestmann provided planning and design consultation globally through his firm until his retirement. Beginning over 20 years ago, he was tapped by the US Army Corps of Engineers and the Natural Resources Conservation Service to provide international technology transfer to assist in the adoption of engineering and construction practices compatible with sustainable water and habitat management.

NAUE America Receives Honor from Emergency Training Center
08/27/2010
The expansive Smokey Hill Air National Guard Range near Salina, Kansas provides 34,000 acres for realistic environment training for both active and reserve military organizations. This unique facility includes a 156-acre zone for crisis response training. For the construction of a collapsed structure simulation, site coordinators sought a subgrade reinforcement material that would not require the addition of a separate nonwoven weed barrier. The Kansas Department of Transportation suggested Combigrid® GRK 5 20\20, a material with which KDOT has previous experience. ID:
