But a range of forces have shrunk beaches all along California's coastline．California could lose as much as 75% of its beaches by 2100，given the sea level rise related to climate change．Over time，beach sand gets swept up into the water．Some of it moves towards other beaches．Besides，dams and concrete canals have reduced the amount of river sediment (沉淀物) flowing downstream that could help fill beaches as a supplement (补充)．If the shoreline were allowed to evolve without human intervention，the beaches could continue to exist as we know them．But in California，the development in many places along the coast has created a hard barrier，disturbing that natural evolution．
Over the years，local governments worked together on a few major sand supplement projects．But those，still，have proved to be fleeting solutions．“Everything we do is a short term fix，” said Gary Griggers，a professor specializing in coastal science．In recent years，as the sand's disappearance grew more extreme，longtime Oceanside residents formed an organization called Save Oceanside Sand．A beach town cannot exist without a beach．Leaders here launched some international design competitions，aiming at finding new ways of getting and keeping sand on the city's beaches．
“It's really a race．I think there's absolutely nothing we can do to hold back the Pacific Ocean，” said Gary Griggers．
