Coastal morphology, shoreline stability, and nearshore mineral resources of Upolu, Western Samoa

Description:

A coastal mapping programme was initiated on Upolu Island in Western Samoa as a means of providing a framework within which to identify broad geologic patterns (Roy and Richmond, 1986). The first stage of this programme involved the interpretation of aerial photographs of coastal deposits followed by field verification. Mapping of large areas provides a mechanism whereby the results of more detailed studies can be better applied to the understanding of the entire coastline. The shoreline, reef flats, and coastal plain of Upolu were investigated by a reconnaissance survey designed to examine near shore mineral resources (primarily construction materials), potential geo-hazards, and coastal processes. This report is designed to accompany ten 1:20,000 scale maps (4 sheets) produced of the Upolu coastal zone. Appendix-I provides brief summary descriptions of the reef types, coastal plains, shoreline stability, and resources for each sheet.
