  • 'Big Muddy' Missouri river needs a plan
    on July 11, 2017 at 4:14 pm

    As the Missouri River flows across the Great Plains to where it meets the Mississippi River at St. Louis, it accumulates such a large sediment load that it has earned the nickname 'Big Muddy.' A recent study looks at the history of the river, damages and changes from the 2011 flood, and its current post-flood condition. The study concludes that the river needs a comprehensive plan with multi-state cooperation. […]

  • Rising seas could result in 2 billion refugees by 2100
    on June 26, 2017 at 2:57 pm

    In the year 2100, 2 billion people -- about one-fifth of the world's population -- could become climate change refugees due to rising ocean levels. Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitable places inland, according to new research. […]

  • Engineers shine light on deadly landslide
    on April 26, 2017 at 10:30 pm

    Late in the morning of March 22, 2014, a huge chunk of land cut loose and roared down a hillside in the Stillaguamish River Valley just east of Oso, Washington, about 60 miles northeast of Seattle. In a matter of minutes, 43 people lost their lives as a wall of mud, sand, clay, water. A new report details the factors leading to the disaster, the hazards that accompany landslides and steps that can be taken to mitigate landslide consequences and risk in the Pacific Northwest, with the aim of preventing future tragedies.
