Abstract:

Recent efforts to determine worldwide patterns of shoreline change have been stimulated by growing property losses from such coastal problems as erosion, flooding, and storm surges. Much of the damage stems directly from the growing intensity of construction and development along coastlines, among the most hazardous of the worlds environments. But losses in many locations have been inexplicably large, raising speculation that changing patterns of shoreline erosion may be partially responsible. Although the 500-kilometer-long Oregon coast has been classified as retrograding-submergent and displays landforms deserving of such a classification, measurable retrograding within the past century has been confined to a relatively small part of the shoreline. Comparison of early maps and 1939 air photos with more recent imagery indicates that most of the sandy shore has been stable, with some evidence of isolated prograding.
