Abstract


The sudden occurrence of abrasion disaster in Amurang Beach, resulting in the loss of some areas, requires geospatial technology-based studies to understand the dynamics of coastal morphology. This research aims to analyze the changes of Amurang shoreline after the abrasion disaster with a time-lapse approach based on Unmanned Aerial Vehicle (UAV) imagery. The research study was descriptive quantitative with remote sensing approach. The analysis technique used on-screen digitizing method and time-lapse analysis through baseline and comparative data. Baseline data was obtained through UAV imagery acquisition (2023) to represent the latest post-disaster conditions. Meanwhile, comparative data was used to compare shoreline changes before and after the event, including satellite imagery (2021) and UAV imagery (2022). Based on the time-lapse analysis, the overlay of the dataset processing results showed that the comparison of shoreline position experienced a significant impact with a reduction in area of 3.07 hectares within 2 years. The quantification of other metrics revealed the existence of critical abrasion patterns divided into two categories. The Extreme Abrasion Zone, located at the front of the Ranowangko River estuary, experienced a shoreline shift of up to 130 meters. Where thematic objects such as built-up land, transportation networks, and residential areas experience landslides into the sea. The Medium Abrasion Zone, occurring at the closest side of the river mouth, which is also affected by erosion, experiences a shoreline shift or moves back towards land by < 90 meters. Utilization of UAV data acquisition provides high precision in documentation of abrasion impacts and identification of abrasion-prone zones. This study recommends the integration of UAV data with comprehensive advanced analysis to predict future coastal morphology dynamics, so as to support more adaptive and proactive data-driven mitigation policies
