In 2006, the US Geological Survey (USGS) issued a news release about a report it conducted concerning California's changing shoreline. Read the following passage from the news release.1 Coastal Beach Erosion on the Increase in California
An important finding from the report concludes that the net shoreline change in the short-term (25-40 years) indicates that 66 percent of California´s beaches are eroding. . . . Long-term coastal shoreline change (using data gathered over the last 120 years) shows a trend of expansion, which is likely attributable to large scale coastal engineering and beach nourishment projects in Southern California, and to a high influx of sediments from coastal rivers in Northern California. . . .

California is the most populous state in the union and has a particularly close relationship with its coastal ocean. Two of the five largest metropolitan areas in the nation border the sea in California and residents depend upon the sandy shoreline and ocean for recreation, commerce, security and navigation. As a result of these activities, the ocean and beaches are sometimes at risk, the coastline has changed, channels and harbors have to be dredged, and coastal and marine ecosystems have been impacted.

The USGS is releasing the first comprehensive analysis of changes to the sandy coastline of California to provide scientific data that will enable both scientists and managers to better understand human impacts to the coast. This historical analysis of past and present trends of shoreline movement is designed to allow for future repeatable analyses of shoreline movement, coastal erosion and land loss. The study is likely to provide a baseline for coastal change information for a wide variety of coastal management decisions.
