- 요약Climate change is increasing the rates and severity of natural hazards worldwide. With a large portion of the global population living along coasts, increases in hazards, particularly coastal hazards, pose an increasing risk to communities. Better understanding of risk and the uncertainty of that risk is necessary to increase the resilience of our societies as they face increasing stresses. To this end, this dissertation contributes to the following objectives: modeling subsurface conditions including their uncertainty, quantifying climate risk from a multi-hazard perspective, and considering risk reduction techniques and the social outcomes of disasters. Within these broad objectives, each chapter provides specific contributions.The first objective to model subsurface conditions with uncertainty is supported by Chapter 2 which simulates layers of hydraulic conductivity and by Chapter 3 which quantifies regional liquefaction hazard and risk. Both projects utilize detailed soil data from cone penetration tests (U.S. Geological Survey, 2002) to simulate soil properties across the subsurface, considering uncertainty in modeling parameters. Applied to a case study of Alameda, CA, the proposed approach simulates groundwater levels that agree better with empirical data than previous models, giving higher confidence to simulations under sea level rise. In addition, qualitative and quantitative sensitivity studies show the importance of different modeling parameters to inform future application to probabilistic simulations. Chapter 3 expands liquefaction potential index from single point locations to a regional context through a 3D subsurface soil property model. This methodology calculates probabilistic liquefaction risk that considers uncertainty in spatial subsurface properties. These baseline condition and hazard models contain uncertainty that can be propagated through full risk analyses.The second objective to quantify climate risk from a multi-hazard perspective is addressed by Chapter 4. This project defines a multi-hazard framework with statistically independent hazard pathways that are summed to quantify total multi-hazard risk. Climate risk is quantified as the change in multi-hazard risk under scenarios of future climate. For a case study of Alameda, sea level rise risk is quantified as the increase in loss to residential housing under various amounts of sea level rise. This risk can be disaggregated by hazard and assessed spatially to understand which assets have the highest climate risk. Community-level risk can also be tracked over time under different climate scenarios to understand how the increase in risk compares to the levels of climate change. For the Alameda case study, while earthquake and liquefaction risk is dominating at present-day, under 1 m of sea level rise, coastal flooding risk is expected to exceed the annual risk of losses due to earthquake. Climate risk is somewhat localized to neighborhoods with high projections of coastal flood risk, informing areas where adaptation strategies should be prioritized.The third objective to consider social outcomes of disasters and enable risk reduction is met by Chapter 5, which presents a housing recovery model that includes multiple categories of housing including multi-family and rental units, and by Chapter 4, which quantifies risk reduction achieved by different adaptation strategies. The housing recovery model accounts for financing programs available for buildings of various types and tenures, and a case study for a Hayward earthquake event in Alameda, CA, reflect that despite comparable initial damages, multi-family housing takes longer to recover and has a higher rate of not obtaining the necessary financing to repair.
