Abstract: Shoreline change at the Colorado River mouth, Texas, was estimated based on survey results from 1990 to 1992 and some historic data. In terms of the long-term variation, the shoreline in the north section is accretional. From 1984 to 1990, an area of 63,000 m2 was gained within the north section. On the other hand, some severe erosion can be caused by storms. Complex PCA was applied to analyze a fast-moving bar event. It showed significant advantages over the conventional PCA. Using fewer components, CPCA can explain more variations. The results of reconstruction by CPCA reflected the variation in the observed data set well. Volume changes in profiles were selected as variables for principal component analysis. Using the results, variation alongshore was detected. Further use of this method is expected to be fruitful.
