Scientists See Sand's Future: "For years scientists have understood how pounding waves during violent storms suck sand offshore. How it reappears on beaches once the stormy seas have passed, however, remains a mystery, and without that information, accurately predicting beach evolution has been impossible. Now researchers are one step closer to foretelling sand's journeys. A model that successfully forecasts how sandbars that protect beaches from harsh wave action migrate away from shore and back again over several weeks is described today in the journal Science."
