124. Changes on the northeast side of St. Helena Sound, Fish Creek 

 Inlet, and South Edisto River Inlet have been adequately represented by the 

 shoreline change mapping. Likewise, shoreline changes surrounding a small, 

 unnamed inlet just south of Frampton Inlet on map 9 are also represented by 

 the shoreline change mapping technique; however, it had some small alongshore 

 changes as well. From 1851/54 to 1920/21, it moved slightly northeast; and 

 from 1920/21 to 1933, it moved southwest. Since 1933, it has remained sta- 

 tionary in its alongshore position. 



Frampton Inlet (Map 9) 



125. At Frampton Inlet, from 1851/54 to 1933, there were two tidal 

 creeks that merged to form one inlet, similar to previously discussed 

 Pritchards Inlet. Inlet throat width was approximately 180 m in 1851/54 and 

 120 m in 1933. During this interval, the throat migrated northeast. Between 

 1933 and 1964, throat width increased to 420 m, by alongshore retreat (610 m) 

 on the southwest side of the inlet relative to 300 m of elongation on the 

 northeast side. By 1970/74, additional alongshore losses on the southwest 

 side (120 m) had combined with movement of the northeast side of the inlet 

 610 m to the northeast and separation into two inlets. On the 1983 survey, 

 two distinct inlets, each about 300 m wide, are separated by approximately 

 900 m of shoreline. The southwest spit moved southwest an additional 120 m, 

 and the northeast spit retreated 240 m as the inlets migrated apart. 



North Edisto River Inlet (Map 9) 



126. Over the time range of data used in this study, there has been 

 little alongshore migration of North Edisto River Inlet. Most change has been 

 in the onshore/offshore direction. The southwest side of the inlet has 

 retreated landward steadily since 1851/54. The northeast side advanced sea- 

 ward from 1851/54 to 1933, was stable to 1964, and advanced slightly from 1964 

 to 1970/74. From 1970/74 to 1983, it eroded back to about the 1964 position. 

 Onshore/offshore changes resulted in widening of the inlet throat southwest- 

 ward from approximately 975 m in 1851/54 to 1,830 m in 1964, to approximately 

 1,890 m in 1983. The magnitude of the onshore/offshore changes are given in 

 Appendix A, Map 9, sections 4 through 9. 



127. Deveaux Bank, which sits at the inlet mouth has undergone dramatic 

 changes since it was first mapped in 1920/21. At that time, it was approxi- 

 mately 150 m long, extending in a north-northwest, south- southeast direction, 

 and had approximately 24,000 m 2 of subaerial surface area. By 1933, it
