De-authorizing navigation on the Missouri River would do wonders to ensure a robust water supply for irrigation and recreation in the Midwest—although at a cost to certain interest groups, many of them downstream.

Every option is on the table as the U.S. Army Corps of Engineers launches a study to challenge whether the “eight purposes” enshrined in a 66-year-old federal act that governs water management policy on

A joint U.S.-European group has presented the low bid to analyze the options for a vehicular crossing at the Atlantic entrance of the Panama Canal, officials said on Monday. Photo: C.J. Schexnayder The Third Lane Expansion project will be built roughly at the site of a previous excavation by the U.S. Army Corps of Engineers, visible to the left of the Gatun Locks. San Francisco-based URS Corp. and the Danish firm COWI A/S submitted a bid of $895,000—the lowest of five tendered—to examine the possibilities of a permanent crossing at the historic waterway’s Atlantic entrance that will allow uninterrupted traffic

The U.S. Environmental Protection Agency declared on March 2 that the Gowanus Canal will be added to the list of federal Superfund cleanup sites. The heavily polluted canal runs through an old industrial sector in the New York City borough of Brooklyn and empties into New York harbor. EPA’s decision will set in motion a $500-million, decade-long effort to clean up the former industrial canal, which EPA says is contaminated with PCBs, coal-tar waste, heavy metals and volatile organics. Mayor Michael Bloomberg (R) had opposed the EPA designation, fearing it would endanger real estate developement plans for the area. EPA

Hours after Chile was hammered on Feb. 27 by one of the most powerful earthquakes in its history, President Michelle Bachelet made it clear the country already is preparing for recovery. Photo: AFP/Getty Images The naval port city of Talcahuano, about 20 km from Concepción, was devastated by a tsunami about an hour after the quake, catching unwarned residents by surprise. No tsunami warnings were issued for Chile’s coastal towns.

The most powerful earthquake to strike Chile in a generation may have left hundreds dead and the South American nation’s infrastructure in tatters, yet the fact the destruction was not far worse is being cited as a testament to Chile’s application of improved building codes and decades of efforts to prepare. Slide Show Photo: AP/Wideworld Nine died and seven were missing—with some believed trapped alive behind a wall that took the load—when the 70-unit Alto Rio Apartment complex in Concepción rolled off its foundations in the Feb. 27 quake. Investigators likely will study the structure’s perfomance for what worked and

Six years after design began and one year after it was completed, Egypt’s Ministry of Culture is almost ready to start construction of the $550-million main building of the Grand Egyptian Museum, near Cairo.

Having secured a $390-million soft loan from Japan, the ministry last month appointed a team of Hill International Inc., Marlton, N.J.,

The U.S. Army Corps of Engineers and levee districts throughout Mississippi River Watershed are preparing for potentially imminent floods by drawing on a battery of strategies, the first of which is keeping a close watch on weather patterns, water levels and soil conditions.

A multidisciplinary team of U.S. earthquake researchers and design engineers, organized by the Earthquake Engineering Research Institute (EERI), is leaving Feb. 28 to spend six days in Haiti. The team, under the leadership of Reginald DesRoches, Professor and Associate Chair of the School of Civil & Environmental Engineering at Georgia Institute of Technology, will document scientific, engineering and societal effects of Jan. 12’s magnitude-7 earthquake. The goal is to focus on the disaster’s impacts on people, the performance of structures and lifelines, and the enormous societal challenges of relief, recovery and rebuilding, says the Oakland, Calif.-based EERI. Team members plan

The largest dam removal and river restoration project in U.S. history moved a step closer to reality last month as the U.S. Dept. of the Interior, Oregon, California, PacifiCorp and about 40 other groups signed agreements that will set into motion the $200-million removal of four dams on the Klamath River and the $1-billion restoration of the Klamath Basin.

The Tom Bradley International Terminal at the Los Angeles International Airport on Feb. 22 kicked off construction of the new $1.5-billion Bradley West modernization project. The project comprises 1.25 million sq ft of new building area, including food/beverage and retail concessions, new premium lounge space, enlarged federal inspection/customs and border-protection facilities, and 15 new boarding gates. Enlarged passenger-seating/holding-room areas will be sized to accommodate the newest generation of aircraft, including the Airbus A380 super-jumbo jet and the Boeing B787 Dreamliner. Fentress Architects of Los Angeles designed the upgrade, and Walsh Austin Joint Venture of Los Angeles will construct it. The
