Abstract: The rapid degradation of coastal infrastructure due to climate change, sea level rise, storm surges, and increasing frequency of extreme weather events has created an urgent demand for innovative monitoring and resilience strategies. Remote sensing technologies, combined with geotechnical engineering approaches, provide an integrated solution for assessing, monitoring, and mitigating the risks to coastal structures. Satellite imagery, LiDAR surveys, Synthetic Aperture Radar (SAR), and Unmanned Aerial Vehicles (UAVs) enable large-scale and high-resolution mapping of coastline changes, infrastructure deformation, and sediment transport. These datasets, when coupled with geotechnical models, assist in predicting foundation stability, shoreline retreat, and infrastructure vulnerability. This paper examines the synergy between remote sensing and geotechnical approaches for building resilient coastal infrastructure. It highlights applications, methodologies, case studies, and challenges, with a focus on proactive resilience planning
Keywords: Coastal infrastructure, remote sensing, geotechnical engineering, resilience, SAR, LiDAR, UAV, shoreline monitoring
