A study on erosion at Ocean Beach, California found that reduced sediment supply from San Francisco Bay has caused erosion by shrinking the ebb-tidal delta. This has changed wave patterns and circulation, leading to persistent erosion. Additionally, a sewage outfall pipe has created a local depression in wave heights, further contributing to erosion.
