Disaster-resilient coastal infrastructure design entails theoretical considerations of integrating natural and engineered solutions to protect coastal communities, infrastructure, and ecosystems from coastal hazards, such as erosion, flooding, and storm surges, while enhancing resilience and adaptive capacity to changing climate conditions. Construct a detailed theoretical framework delineating principles of disaster-resilient coastal infrastructure design methodologies, including shoreline protection measures, ecosystem-based adaptation strategies, and coastal land use planning. Explore theoretical models for assessing coastal infrastructure vulnerabilities, such as hazard mapping, vulnerability assessment, and cost-benefit analysis, and discuss theoretical approaches to implementing coastal resilience measures, such as beach nourishment, dune restoration, and setback regulations, aiming to enhance coastal resilience, reduce risk, and promote sustainable development along coastal zones.
