Tybee Island is a barrier island located immediately south of the mouth of the Savannah River. Natural processes and modifications introduced by man have promoted a complex history of shoreline evolution which has important implications for other 'developed' barrier islands. Periodic reorientation of the shoreline has caused a history of localized erosion and localized protection efforts. This has resulted in the sequential construction of numerous groins, seawalls, and revetments, in addition to periodic beach nourishment activities. Each of these efforts is analyzed and presented along with a review of the various engineering and geologic studies which have been conducted over the last 50 years. The current status of erosion and erosion control efforts is presented. Recommendations are also offered. Keywords: Beach erosion; Shore protection; Coast changes; Coastal engineering.
