1962/63. Rate of accretion varied from 15 m/year up to 46 m/year during the 

 1926 to 1934 period. This resulted in a southerly inlet migration with cor- 

 responding downdrift erosion. Inlet throat width decreased from approximately 

 180 m in 1872 to 90 m in 1962/63. Between 1962/63 and 1983 surveys, the 

 inlet's northeast side eroded, reducing spit length approximately 490 m. 

 South side accretion kept the inlet throat around 100 m wide. 

 Midway Inlet (Map 22) 



154. The northern side of Midway Inlet eroded 180 m alongshore between 

 1872 and 1926. This northeastward erosion was followed by rapid southwestward 

 accretion (240 m) between 1926 and 1934. A more modest rate of accretion 



(11 to 15 m/year) continued to 1983 for a net (1872-1983) southwest growth of 

 670 m. Inlet changes on the south side are inversed, with accretion of over 

 300 m between 1872 and 1926 and steady erosion (690 m) between 1926 and 1983. 

 Inlet throat width narrowed from 275 m in 1872 to 150 m in 1926 and then 

 increased to over 1,000 m in 1934. From 1934 to 1983, throat width decreased 

 steadily to only 60 m. Net change from 1872 to 1983 was a narrowing of the 

 inlet by just over 200 m. 

 Murrells Inlet (Map 23) 



155. Murrells Inlet 1872 survey shows a long northeast trending spit 

 extending southwest. The inlet throat, about 300 m wide in 1872, is in its 

 most southerly position. Between 1872 and 1926, the long spit severely eroded 

 northeasterly (1,950 m) while a new spit grew (2,280 m) toward the northeast 

 from a southerly point along Magnolia Beach. This resulted in shoal accretion 

 south of the inlet. Inlet throat width increased to 850 m as Murrells Inlet 

 migrated to a northerly position. From 1926 to 1934, this south side spit 

 continued to advance northeastward approximately 300 m. North side accretion 

 (180 m) resulted in narrowing of the inlet to 300 m by 1934. From 1934 to 

 1963, erosion/accretion patterns reversed, with over 850 ra of alongshore ero- 

 sion south of the inlet and 580-m growth of a new spit on the north side. 

 Inlet width increased to 670 m as it migrated south. South side erosion and 

 north side accretion continued to the 1969/70 survey. Jetty construction 

 occurred in 1977-1980. The 1983 survey shows no change in north side spit 

 length since 1969/70, with mild accretion to the south (30 m) . Throat width 

 decreased slightly from 640 m in 1969/70 to 580 m in 1983.
