Abstract/Summary Aset of groynes and breakwaters were constructed in 1956 around the Salaverry Maritime Terminal in the northern coast of Peru to facilitate port operations. As a result, part of the longshore transport was blocked, producing undesirable impacts along the coastline. Apart from local bathymetric monitoring, a thorough shoreline change assessment has not been carried out. The aim of this study is to quantify shoreline change donwdrift of the Terminal using a combination of mapping techniques. Erosion/accretion rates were estimated using GIS, yielding an average erosion rate of 3.2m/year between 1976 and 1997, with a maximum of 7.6m/year. Despite limitations on data availability and quality, results were consistent with field observations and point measurements from aerial photographs. The potential mapping error to actual shoreline variation ratio is small and outcomes of this study can be considered statistically reliable. The integration of qualitative and quantitative data into a GIS framework is the most effective method to model erosion hazards.
