Flooding could affect one out of every 50 residents in 24 coastal cities in the United States by 2050, a study led by Virginia Tech researchers suggests. The study, published this month in Nature, shows how the combination of land subsidence—in this case, the sinking of shoreline terrain—and rising sea levels can lead to the flooding of coastal areas sooner than previously anticipated by research that had focused primarily on sea level rise scenarios.
