Coast of California Storm and Tidal Waves Study. Shoreline Movement Data Report. Portuguese Point to Mexican Border (1852-1982),
Abstract
This report describes the results of a cooperative study of shoreline movement conducted as part of the Coast of California Storm and Tidal Waves Study (CCSTWS). The study area comprised the Pacific Ocean coast from Portuguese Point. CA, (Near Los Angeles) south to the United States/Mexico Border, a distance of approximately 125 miles. Changes in shoreline position ranging from as early as 1852 or as late as 1959, up to 1982, are analyzed using survey data from NOAA's National Ocean Service (NOS) and its predecessor, the U.S. Coast and Geodetic Survey. A series of shoreline movement maps for this coastal reach produced by NOS is intended to accompany this report. This report provides a basic data set for use in management and engineering decisions related to the coastal zone. It is designed primarily to describe and partially quantify shoreline movement maps that accompany it. Average yearly land area and shoreline movement rates of change were calculated for each minute of longitude for the area from Portuguese Point south to Anaheim Bay (east-west-trending shoreline), and for each minute of latitude from Anaheim Bay to the U.S./Mexico border (north-south trending shoreline). The sole purpose of this report is to describe and quantify historic shoreline movement. No attempts were made to identify or even speculate on the reasons for these movements. Keywords: Sediment transport; Coastal processes; and Shoreline movement.
