Abstract
Analysis of air photographs and maps indicates complex patterns of shoreline changes along the south coast of Vere, Jamaica, between the mouths of the Rio Minho and Milk River. These include up to half a kilometre of shore-normal coastal recession between 1941 and 1991, the largest known shoreline change in Jamaica over the past 60 years. Previously, the coastline had been prograding seawards from a low cliff cut into the Rio Minho alluvial fan, in the process constructing a shore-parallel ridge and lagoon complex. The cliff itself is evidence of earlier coastal erosion. Maps published in 1804 and 1885 confirm the mobility of this coastline in historical times. They suggest that the more easterly complex of shore-parallel lagoons was constructed prior to about 1880, while the more recent, westerly beach ridges developed, at least partly, from progressive destruction of the lagoon complex, following a change in orientation of the Rio Minho mouth in the late 19th Century. Photographs of 1999 indicate the onset of accretion, probably resulting from the gradual onshore movement of massive quantities of sediment deposited off the Rio Minho mouth during the extreme flood event of 1986 and several lesser events in 1988 and the 1990s.....
