  • How much soil goes down the drain: New data on soil lost due to water
    on December 15, 2017 at 5:10 pm

    According to a new study, almost 36 billion tons of soil is lost every year due to water, and deforestation and other changes in land use make the problem worse. The study also offers ideas on how agriculture can change to become a part of the solution from being part of the problem. […]

  • The planet’s largest landslides happen on submarine volcanoes
    on December 12, 2017 at 4:48 pm

    Large volume submarine landslides, triggered by the inception and growth of submarine volcanos, represent among the largest mass movements of sediment on Earth’s surface. These landslides could potentially cause tsunamis, and represent a significant, and as yet unaccounted for marine hazard. […]

  • One in ten historic coastal landfill sites in England are at risk of erosion
    on November 16, 2017 at 12:52 am

    There are at least 1,215 historic coastal landfill sites in England, mostly clustered around estuaries with major cities, including Liverpool, London, and Newcastle on Tyne. An investigation by researchers finds that 122 sites are at risk of starting to erode into coastal waters by 2055 if not adequately protected. […]

  • Changing climate to bring more landslides on logged land, say researchers
    on November 9, 2017 at 2:32 pm

    Researchers say landslides on logged forests will be more widespread as the Northwest climate changes. In a study modelled on clear-cut lands on the Olympic Peninsula, they anticipate the climate of 2045 and conclude that there will be a 7 -11 percent increase in the land that is highly vulnerable to landslides. The researchers say their findings are applicable to the Cascade Mountain Range area as well. […]

    on October 23, 2017 at 10:25 pm

    Rising sea levels caused by a warming climate threaten greater future storm damage to New York City, but the paths of stronger future storms may shift offshore, changing the coastal risk for the city, according to a team of climate scientists. […]

  • Why did the 2014 Oso, WA, landslide travel so far?
    on October 23, 2017 at 10:25 pm

    On Saturday, 22 March 2014, a devastating landslide roared across the North Fork of the Stillaguamish River, near Oso, Washington. The landslide killed 43 people as it plowed through the Steelhead Haven neighborhood. When it stopped, after crossing the river, the neighborhood, and State Route 530, the Oso landslide had traveled 1.4 kilometers. […]

  • Salmon sex linked to geological change
    on October 19, 2017 at 2:08 pm

    It turns out that sex can move mountains. Researchers have found that the mating habits of salmon can alter the profile of stream beds, affecting the evolution of an entire watershed. The study is one of the first to quantitatively show that salmon can influence the shape of the land. […]

  • Forest grazing counteracts the effectiveness of trees to reduce flood risk
    on October 10, 2017 at 3:46 pm

    Planting trees can reduce flood risk, but a high intensity forest land use, such as grazing, can counteract the positive effect of the trees, a recently published study suggests. The study investigated the rate that water infiltrated the soil under trees at an experimental agroforestry site in Scotland. […]

  • Preservation of floodplains is flood protection
    on September 27, 2017 at 2:23 pm

    The silting of rivers and streams leads to problems for fish, mussels, and other aquatic organisms because their habitats disappear. However, not only intensive agriculture and erosion are destroying these habitats. Now a study refutes this widespread view. In order to save the species living in the river basin -- and protect people from the threat of floods -- rivers need more space, diversity, and freedom. […]

  • Removing nitrate for healthier ecosystems
    on September 27, 2017 at 1:33 pm

    In a new study, researchers have identified nitrate removal hotspots in landscapes around agricultural streams. […]

    on September 26, 2017 at 12:59 pm

    A new study discusses triggers of the Saint-Jude landslide in Quebec that occurred in nearly 10,000-year-old sensitive clay sediment that 'liquefies' when disturbed. […]

  • Decade of data shows FEMA flood maps missed 3 in 4 claims
    on September 12, 2017 at 9:05 pm

    An analysis of flood claims in three Houston suburbs from 1999-2009 found that the Federal Emergency Management Agency's 100-year flood plain maps failed to capture 75 percent of flood damages from five serious floods, none of which reached the threshold rainfall of a 100-year event. […]

  • Increasing effective decision-making for coastal marine ecosystems
    on September 7, 2017 at 2:23 pm

    Marine restoration, rather than protection, might be the most cost-effective solution for coastal marine ecosystems suffering from human activities, a new study has found. The study examined how to best benefit coastal marine ecosystems on limited conservation budgets, to help managers better understand the trade-offs. […]

  • Digging in the dirt: Researchers develop new methods for assesing risk of subsurface phosphorus
    on August 17, 2017 at 2:07 pm

    New methods for assessing the loss of phosphorus in soil have now been developed by researchers. While current measurements focus mainly on surface runoff, the new research is looking at the best way to measure the risk of underground phosphorus that winds up in drainage water. […]

  • Florida flood risk study identifies priorities for property buyouts
    on August 17, 2017 at 1:28 pm

    A study of flood damage in Florida proposes prioritizing property buyouts based on flood risk, ecological value, and socioeconomic conditions. Forecasters say an above-normal hurricane season is likely in the Atlantic Ocean this year, while a rising sea level is making Florida increasingly vulnerable to dangerous flooding. […]

  • Climate change shifts timing of European floods
    on August 10, 2017 at 6:15 pm

    A linkage between climate change and floods has been identified using a river flow dataset of unparalleled scale and diversity. This is the first time this link has been demonstrated at a continental scale using observational data. […]

  • The only way is up: Trees help reptiles thrive
    on August 10, 2017 at 2:49 pm

    If graziers leave trees in place on their land, all types of reptiles will benefit, investigators suggest in a new report. […]

  • Complex causes of Maldives flooding
    on August 7, 2017 at 12:23 pm

    The causes of coastal flooding in the Maldives are more complex than previously thought, according to a new study.

  • Invasive plant species can enhance coastal ecosystems
    on July 17, 2017 at 7:08 pm

    Invasive plant species like seaweed can provide vital ecosystem functions in coastal areas where native habitats such as salt marshes and oyster reefs have severely declined. A new study finds that invasive species could be used to offset the loss of native habitats that provide storm protection, food production and other benefits to billions of people. […]

  • Mississippi mud may hold hope for Louisiana coast
    on July 13, 2017 at 12:11 am

  • '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. […]
