Widening beaches make California 500 acres bigger than it was 40 years ago

Southern California's beaches have grown more than 500 acres over the past four decades despite being one of the most heavily urbanized and dammed coastal regions in the world, according to a new study conducted by researchers at the University of California, Irvine, the U.S. Geological Survey and other institutions. The conventional wisdom-challenging revelation about coastal erosion and replenishment is the subject of the study published recently in Nature Communications.
