Critical surge barrier on New Orleans's eastern flank completed ahead of schedule
A 7,490 ft.-long storm-surge protection wall that is the central part of a roughly two-mile long surge barrier in New Orleans is being completed several months ahead of schedule; the placement of a significant portion of the barrier, well ahead of the start of the 2010 hurricane season, adds a welcome level of defense on the city’s eastern flank

Louisiana officials to visit the Netherlands to learn Dutch flood protection methods
The Dutch are widely hailed as having the best investment in flood protection in the world; much of the country’s densely populated areas are below sea level, and after a storm struck in 1953 and flooded 80 percent of the Netherlands, the Dutch became even more serious about flood protection

To avoid cyberwar and protect infrastructure -- fight cybercrime first
Fighting cybercrime is the first step to avoiding cyberwar, protecting infrastructure; Christopher Painter, the White House’s senior director for cybersecurity: “There are a couple of things we need to do to harden [critical infrastructure] targets” — “But the other thing you need to do is reduce the threat. And the predominant threat we face is the criminal threat — the cybercrime threat in all of its varied aspects”

Fiber polymer replaces steel bars in major building projects
UAE University researchers have developed an inexpensive alternative to demolishing damaged buildings and rebuilding them: using FRP (fiber reinforced polymer); FRP can be used in strengthening and repair instead of concrete or steel jacketing, which are labor intensive; moreover, concrete and steel jacketing systems are also often vulnerable to the same deterioration mechanism that caused the problem in the first place

Studies agree on a rise in sea levels of between 0.7 and 1.2 meters during the next 100 years
A joint study by universities and research institutions from England, China, and Denmark finds that IPCC 2007 estimates that sea level would rise by less than half a meter in the next 100 years were too low; the researchers now estimate that sea levels will rise between 0.7 and 1.2 meters during the next 100 years; instead of using temperature to calculate the rise in sea levels, the researchers have used the radiation balance on Earth — taking into account both the warming effect of greenhouse gasses and the cooling effect from the sulfur clouds of large volcanic eruptions, which block radiation

Study: U.S. Northeast seeing more, fiercer rainstorms
Rainstorms in the U.S. Northeast have become more frequent and fiercer over the last six decades; there is a debate whether or not this 60-year trend is an indication of, or is related to, global warming; what is more certain is the potential economic impact should the 60-year trend continue, requiring billions of dollars in infrastructure improvements to things in the region including roads, bridges, sewers, and culverts

Troubled bridges: remote monitoring of bridges' health nears
As with people, bridges start getting sick long before they develop obvious symptoms; researchers develop remote-sensing technologies for monitoring the health of bridges; with on-site inspections occurring only once every two years, remote monitoring a bridge’s condition is the best way to assure the health of bridges

New software spots vulnerabilities in flood defenses
Spanish researchers develop a computer system could provide more detailed flood-risk information; the system developed at Universidad Politécnica de Madrid (UPM) identifies flood risks more quickly and effectively than satellite imagery, particularly in areas where there are dramatic changes in land over small spaces

India to build a hunter-killer UAV fleet; UAVs will come from Israel
India is set to augment its fleet of reconnaissance UAVs with killer-hunter UAVs; the Indian military has been impressed with the effectiveness of the UAV campaign against al Qaeda and the Taliban in Afghanistan and Pakistan, and wants to adopt the same approach to India’s problem with Muslim terrorists; Israel, which sold India the intelligence-gathering drones, will be the source of the attack UAVs as well

Cyber espionage targets UAV manufacturers
A report tracking cyber-espionage — and cyber-industrial espionage — against U.S. defense contractors finds an intriguing trend: targeting UAV technology; UAVs are likely to remain a principle target of foreign collection activities, particularly given the growing market in UAVs, the report notes

Federal IT professionals: Cyberattack on U.S. critical infrastructure looming
More than half of federal IT professionals surveyed believe the potential is “high” for a cyberattack from a foreign nation against critical IT infrastructure in the next year; moreover, 42 percent of them think the U.S. government’s ability to prevent or handle such an attack is merely fair to poor.

Hearing to be held on lack of chemical plant inspections
There are about 15,000 chemical plants in the United States; 6,000 of them were supposed to be inspected by DHS to make sure their security protocols comply with the current Chemical Facility Anti-Terrorism Standards program, or CFATS, but only 12 have been inspected

Protecting structures by tracking down rust
Damage to concrete bridges caused by rust can have fatal consequences, at worst leading to a total collapse; now, researchers have developed an early-warning system for rust; sensor-transponders integrated in the concrete allow the extent of corrosion to be measured

The lessons of Chile earthquake to California building code
Since the Chile earthquake, many U.S. engineers have visited Santiago and other affected cities to study the failures and successes of building codes here; Chile is of particular interest to American engineers because it employs similar building codes to those in California and also has widespread use of reinforced concrete; one observation from Chile’s earthquake that could find its way into U.S. building code concerns confining reinforcement; confining reinforcement is meant to keep vertical bars from bucking, but the design proved insufficient in Chile; one solution: requiring confining reinforcement along a greater length of the wall

Water Wars: A Historic Agreement Between Mexico and US Is Ramping Up Border Tension
As climate change drives rising temperatures and changes in rainfall, Mexico and the US are in the middle of a conflict over water, putting an additional strain on their relationship. Partly due to constant droughts, Mexico has struggled to maintain its water deliveries for much of the last 25 years, deliveries to which it is obligated by a 1944 water-sharing agreement between the two countries.
