Like all coasts, the land around the Mississippi River is constantly evolving. In past centuries, that process was slowed by the annual flooding of the River’s vast delta, which brought new sediment to replace what was lost.
But climate change, coupled with better engineering (which brought effective channeling and stronger levees), have turned this coastline into one of the most rapidly eroding areas of the U.S. In the area around Buras, gone are the formerly distinct waterways of English Bay, Bay Jacquin, and Scofield Bay, leaving a vast expanse of water between the mainland and the barrier islands.
It’s no secret that Boulder, Colo., was likely to experience a major flash flood at some point. Located at the base of the Rocky Mountains, the city rests up against a canyon from which a creek runs through Boulder, nearly cutting it in half. The Boulder Creek has been called the No. 1 flash flood risk in Colorado, and 15 creeks with flood plains affect more than 15 percent of the city. Cementing the likelihood of a major event, in 2004, the University of Colorado at Boulder’s Natural Hazards Center listed a flash flood in Boulder as one of six “disasters waiting to happen” in the U.S.
And though few may have expected what the National Weather Service described as “biblical rainfall amounts” in the second week of September, Boulder was prepared for the flash flooding that followed the torrential rainfall — the city and county’s engineers, scientists and emergency managers had been preparing for decades.
Louisiana’s Coastal Protection and Restoration Authority on Wednesday approved a $725 million plan for fiscal year 2015 that includes $477 million for construction of levees and coastal restoration projects.
The unanimous vote moves the plan to the Legislature for final approval.
The biggest expenditures in 2015 will be aimed at rebuilding barrier islands and headlands and beginning the design and construction of sediment diversions, using money the state will receive from settlements involving the BP Deepwater Horizon oil spill.
How Offshore Wind Turbines Could Have Calmed Hurricane Katrina and Superstorm Sandy
According to new research, a giant wind farm off the coast of New Orleans in 2005 could have lowered the wind speeds of Hurricane Katrina by between 80 and 98 miles an hour and decreased the storm surge by 79 percent.

This house by Baca Architects can float in 8 feet of water but not float away. Baca Architects appear to have designed a much-needed solution to mitigate the risk of water damage to homes in flood-prone areas of Britain.

Go backward and forward in time with this interactive visualization tool that shows how some of the key indicators of climate change, such as temperature, sea ice extent and carbon dioxide concentrations, have changed in Earth’s recent history.
The Federal Emergency Management Administration on Thursday declared the New Orleans area levee system accredited, clearing the way for the improved storm surge protection to be incorporated into National Flood Insurance Program flood maps, which should eventually lead to reduced flood insurance rates.
