• Dam in Massachusetts raises concerns in Eastern Connecticut

    The condition of 40-year old dam in Massachusetts is deteriorating fast, and communities downstream in Connecticut are worried; U.S. Army Corps of Engineers is looking at ways to shore up the 560 feet long and 78 feet high dam

  • Large dams linked to more extreme weather patterns

    A new study looked at the magnitude of the biggest storms near 633 of the world’s largest dams before and after construction; they found that in many places the level of precipitation in the most extreme rainfall events grew by an average of 4 percent per year after a dam was built, with the relationship especially strong in semi-arid regions

  • New pipe-inspection technology detects leaks in aging pipes

    An aluminum ball slightly larger than a softball travel through hundreds of miles of water pipes and water mains; equipment inside the ball picks up the hissing sounds of any leaks, and the data are then wirelessly transmitted to a computer; after the pipe is drained, workers push the cart, which resembles a steel bike, through the pipe, and electromagnetic coils attached to a computer on the cart detect the location of the leak

  • Vertical evacuation:: Fleeing tsunamis by moving up, not out

    Stanford researchers who have studied the city have concluded that fleeing residents of a city hit by a tsunami would have a better chance of surviving the tsunami if instead of all attempting an evacuation, some could run to the nearest tall building to ride out the wave; this “vertical evacuation” could save thousands of lives, but only if the city’s buildings are reinforced to withstand both earthquakes and tsunamis.

  • Corps speeds testing of tubes for blocking breaches in levees

    Lightweight Universal Gasket, called a PLUG, is a fabric tube that can be floated into place and filled 80 percent with water using an attached pump; the tube is pulled into the breach in the levee by the current, blocking more water from going through the breach; the tube is dropped by helicopter near the breach.

  • Rise in sea levels forces drastic changes on Florida

    If sea levels rise by only two feet, Florida stands to lose almost 10 percent of its land area and the homes of 1.5 million people; the zone which is vulnerable to 27-inch rise in sea level includes residential real estate worth $130 billion, half of Florida’s beaches, two nuclear reactors, three prisons, 37 nursing homes, and much more; the Florida government is considering changes to building codes and other precautionary measures.

  • Rise in sea levels threatens California ports, infrastructure

    Scientists expect ocean levels to rise by at least 16 inches over the next 40 years, causing flooding and endangering facilities throughout the state of California; the California Climate Change Center has estimated that nearly half a million people, thousands of miles of roads and railways, and major ports, airports, power plants, and wastewater treatment plants are at risk; in the Los Angeles-Long Beach-Santa Ana region, sea level rise could expose $96.5 billion of infrastructure to damage.

  • Visualizing climate change in the Bay Area

    Governor Arnold Schwarzenegger unveils the CalAdapt Web site — a Web site developed by the California Energy Commission in conjunction with Google and the Stockholm Environment Institute; the site contains a Google Earth tour, narrated by Governor Schwarzenegger, of projected impacts of climate change on California, including snow pack loss, increased risk of fire, and sea level rises; CalAdapt’s unveiling coincided with the release of the “California Climate Adaptation Strategy,” which outlines recommendations for coping with climate change in urban planning, agriculture, water conservation, and other sectors.

  • New Orleans $1-billion flood defense revised

    To head off a possible $150-million to $300-million cost overrun on the $1-billion Gulf Intracoastal Waterway West Closure Complex in New Orleans, the U.S. Army Corps of Engineers has redesigned the waterway; trading off some “nice to haves” for necessities.

  • Space Time Insight releases upgrade to Crisis Composite for extreme weather

    The new Crisis Composite software for electric utilities correlates the effects of ice storms, hurricanes, earthquakes, and man made events; the solution allows operators of critical infrastructure facilities access to rich geospatial analytics that enable fast, informed action

  • Chemical facility security bills would limit local control

    Water industry insider says that a new bill, creating new chemical security requirements for drinking water utilities, would shift control over security and emergency measures in water treatment facilities from local authorities to the federal government; he is not sure this is a good idea.

  • Growing worries about unregulated chemicals in water

    Concern about pharmaceuticals showing up in drinking water in trace quantities has prompted a growing public awareness of the need to dispose of unneeded pharmaceuticals properly; changing disposal methods will not solve the problem of other organic waste contaminants, because most of them get into the wastewater stream through intended uses, such as bathing and laundering, and because wastewater treatment systems generally are not able to remove them

  • U.S. organize an international meeting on bolstering nuclear plant security

    The fluctuation in oil prices and concerns about climate change have renewed interest in building nuclear power plants; this fact, and the fact that more nuclear material may become available as a result of deep cuts in the U.S. and Russian nuclear arsenals, increase worries about the safety of nuclear materials

  • Florida Power and Light reacts sharply to reports of illegal intruders at nuclear power plant

    FP&L maintains that the Cuban migrants landing on its property did not pose a risk to the Turkey Point Nuclear Power Plant; still, the fact is that 30 Cubans landed in a secure area of the nuclear plant and spent six hours there without being detected by plant’s security personnel; FP&L became aware of the intruders only when they themselves called to control room to announce their arrival

  • How vulnerable is the smart grid?

    The smart grid is a theoretically closed network, but one with an access point at every home, business, and other electrical power user where a smart-grid device is installed; those devices, which essentially put the smarts into the grid, are computers with access to the network; in the same way attackers have found vulnerabilities in every other computer and software system, they will find vulnerabilities in smart-grid devices
