The Evidence of Coastline Changes in Banten Bay, Indonesia

Consisting of semi-circular body, coastal region in the Banten Bay holds a significant role for both marine ecosystem and human activities. The change its coastline due to erosion/sedimentation process may affect economic purposes. This study aims figure out evidence changes using remote sensing numerical model. recording satellite data from Landsat 5 TM, 7 ETM+ 8 OLI during 1990 - 2019, are employed examine Normalized Different Water Index (NDWI). Besides, applying Langevin equation particle tracking model, sediment observation April 2016 utilized simulate trajectory movements understand hydrodynamic processes which cause coastline. Over 30 years, imageries showed with average 0.8 (sedimentation) 0.5 (erosion) km western eastern part respectively. simulation illustrates dominant westward direction maximum 247.88 m3/day supporting sedimentation part. Moreover, distribution suspended demonstrates highest concentration range 9.47 249.54 mg/L indicating intense erosion part.
