• Abstract:
  Sea level variability and intense storm surges present a critical challenge for coastal regions, increasing the risk of wave overtopping and subsequent flooding, with severe implications for public safety, infrastructure, and economic stability. This study develops a comprehensive data-driven stochastic modeling framework integrated with reliability analysis to enhance risk assessment for coastal infrastructure under variable weather-related scenarios. The framework addresses two key objectives: (1) accurately predicting variable sea water levels at critical coastal locations using a stochastic model informed by weather and condition data, enabling proactive planning and risk mitigation, and (2) conducting a quantitative risk assessment of wave overtopping through a reliability-based approach, offering a predictive warning system vital for strategic coastal defense. Additionally, the study incorporates factors such as land subsidence and seawall settlement into the analysis, assessing their impact on the long-term structural reliability of coastal defenses. The Galveston seawall in Texas serves as the test bed for model evaluation, demonstrating its applicability and robustness in real-world scenarios. The findings contribute valuable insights into the design and optimization of resilient coastal protection systems, providing practical tools to address the dual challenges of structural integrity and public safety in the face of weather and condition-induced uncertainties.
