The resilience of Critical Infrastructures in the Presence of Hurricanes
This Critical Resilient Interdependent Infrastructure Systems and Processes (CRISP) project develops an integrated resilience modeling framework for mitigating vulnerabilities in critical interdependent infrastructure systems. The framework evaluates the coupled nature of vulnerabilities across physical and social systems in Miami and Houston. By focusing on the effects of recent hurricanes on the interdependent-infrastructures in energy, water, transportation and telecommunication, and the human-infrastructures interactions, the project explores options for resilience. The system vulnerabilities are quantified with regional inoperability based economic-interdependency models. The project will also develop a mobile phone app for information sharing with the public. Thus, this scientific research contribution supports NSF’s mission to promote the progress of science and to advance our national welfare with benefits that will optimize investments in the nation’s critical infrastructures.
Willingness to Pay and Household Preferences for Sea Level Rise Adaptation Plan
Sea level rise (SLR) is posing a great risk of coastal inundations, flooding, storm surges and other related hazards to coastal areas in Florida. Essential climate adaptation and mitigation plans are crucial in preparing for sea level rise to make our coast and our communities more resilient. A choice experiment survey was conducted to elicit households’ willingness to pay for the Sea level rise related policies. Moreover, the characteristics of households and other factors that determine their preference are explored.
Hurricane Sandy: Utility Disruption and Pathways to Recovery
Utility Disruptions (Electricity, Water, Gas, Phone, Transportation) due to disastrous events can result in direct losses of households’ resilience. Using responses collected through a household survey, the paper estimates the economic impacts of utility disruption on household-level recovery in the aftHurricane hurricane Sandy. The finding suggests that long-term disruptions in utility services are important determinants that increase hurricane-induced damages and delay household recovery levels. Policy attention is thus warned for ensuring rapid restoration of critical infrastructures.
Understanding Non-Evacuation Behavior in Urban Areas During Major Hurricanes
Evacuation behaviors are complex and thus, require continued exploration, especially those pertaining to evacuation timing. The main goal of the study is to figure out the reasons behind low evacuation rate for Hurricane Sandy. Specifically, why do some people stay put, even after mandatory evacuation orders have been issued? Why do others leave when the sun is still shining and the skies are still blue? Employing household survey data with their geospatial information, we hope to 1) identify reasons behind evacuation resistance; 2) estimate the key factor of the Sandy evacuation; 3) identify types of people most/least likely to evacuate; 4) provide implications for public education and future evacuations.
