Abstract:

Coastal protection structures have historically been the most common approach to dealing with the problem of shoreline erosion in the United States. Three potential effects of these structures have been identified and include a impoundment or placement loss, b passive erosion, and c active erosion. The first two are relatively straightforward and predictable for the most part, whereas the third has been the subject of considerable discussion and debate but, until recently, has not been systematically investigated in the field. Four years of monitoring beaches adjacent to seawalls along the central California coast have allowed documentation of the seasonal beach changes that take place in response to the presence of seawalls, and also evaluation of some of the physical processes that influence these changes.
