The article discusses a new method to predict erosion and flooding risks on the U.S. West Coast caused by storms. By analyzing 61 years of wave and water level data, researchers calculated extreme total water levels (TWLs) to assess hazards. They used wave data to estimate wave run-up and combined it with tides and still water levels to predict TWLs. The study found that these extreme TWLs can help determine the likelihood of erosion, overwash, and inundation along the coast.
