【 摘 要 】

It has been argued that seawalls have a detrimental effect on the adjacent beach. These effects may only be noticeable over a period of years or may be short-term effects associated with storms or with seasonal transitions of the beach. Many theories on beach and seawall interaction have been speculative and have lacked actual field or laboratory evidence for their basis. This study uses four years of monthly and post-storm beach profile data to examine what influences the seawalls at Sandbridge, Virginia (USA) have on the adjacent beaches. Long-term effects of the seawalls are analyzed using fourteen years of profile data. Five parameters are defined to describe the subaerial beach profiles. Changes in the profile parameters in time are quantified using three methods of analysis.
