The area in the immediate vicinity of Apia, Western Samoa was studied through the use of air photo interpretations, literature reviews and ground surveys in order to develop an understanding of the processes which influence the coastal and nearshore sedimentary systems. The goal of the study was to provide information on which decisions regarding sand mining and other uses of the coast can be based. In the course of this study it was found that the seaward- facing shoreline on the Mulinu'u Peninsula has undergone variable degrees of change between 1954 and 1990. The most distal portions of the Peninsula (towards the Apia Observatory grounds) have experienced more erosion than locations closer to the town centre. The most severely eroded areas appear to be related to local current patterns on the reef top. The lesser and more variable coastal changes noted near town could be related to more extensive and persistent shore protection rather than any natural causes.
