Summary:Shoreline is defined as the intersection of land and water which provides economic and social security to coastal communities. Semarang is having approximately 20 km shorelines. It faces multiple threats as a result of for instance urban development, industrialization, land reclamation, land subsidence and erosion. In the present study, an attempt was made to monitor the accretion and erosion processes from multi-temporal images from 1988 up to 2017. Fuzzy approach and OTSU method were made to extract the shoreline and DSAS (Digital Shoreline Analysis System) was used to analyse the changes and estimated the shoreline change rate. From change detection results, a general trend of continuous changes of shoreline can be detected representing a vulnerable shoreline affected by human activities. The results of this study can be used to prioritize action and to develop a suitable adaptation measure.
