 abstract={Coastline change is a major issue in coastal development because it affects planning and land use. This study investigates how sediment movement influences shoreline dynamics in northern Semarang. Sediments were analysed at multiple locations using core samples, and shoreline change was assessed using Landsat 5, 7 and 8 imagery (1996–2024) processed in Google Earth Engine together with the Digital Shoreline Analysis System (DSAS). The results indicate a barrier-island system with strong sediment transport. A local change since 2021 is linked to the closure of an inlet channel. Shoreline-change analysis in four-year intervals from 1996 to 2024 shows erosion as the dominant long-term process, causing shoreline retreat, although local accretion was observed at points TRG-01 to TRG-04 associated with channel closure and sediment build-up. Differences between satellite-derived shoreline metrics and granulometric data reflect temporal and spatial variability: erosion is a long-term trend, while accretion represents short-term local change. Overall, the Tugurejo coast is highly dynamic, dominated by erosion but with localised growth in specific sectors.},
