New study reveals Southern California beaches have widened over forty years, contrary to earlier reports of erosion. Researchers found an average gain of twenty-three feet across nearly two hundred miles of coastline. Half the coastline saw significant widening, while thirty-one percent narrowed. Changes affect recreation space and property, prompting emergency fixes. Experts note poor sediment distribution as the main issue. Researchers suggest expanding dredging and nourishment projects for even sand distribution. Frequent satellite monitoring could lead to smarter coastal management.
