Interferometric Synthetic Aperture Radar (InSAR) technology is an operational tool for measuring and monitoring coastal urban stability, including the disappearance of coastal cities. This book provides a comprehensive understanding of how to track climate change impacts on coastal dynamics and their consequent effects on coastal geomorphological changes. Advanced InSAR techniques are discussed, including case studies focusing on the coastal urban areas of Alexandria, Egypt, and Singapore, as well as other potential coastal cities. This book: Describes the use of advanced radar technology for monitoring wave impacts and coastal city damage Introduces new InSAR technologies for assessing coastal infrastructure and urban disappearance Addresses the integration of modern radar interferometry modeling in coastal city sustainability Discusses innovative approaches to model and simulate coastal sediment processes and erosion using space-based interferometry Explores the forecasting of city disappearance and collapse through examples utilizing TerraSAR spot mode data This book is intended for graduate students and researchers in coastal engineering, environmental sciences, remote sensing, computer modeling, and image/signal processing.
