Infrastructure systems – including water, gas, transportation, power, and building systems – are critical to the safety, security, health, and growth of society. Terroristic acts impacting critical infrastructure can have wide-ranging effects on populations and nations. In a post-event scenario, it is critical to have an accurate understanding of the type and extent of damage to facilitate effective emergency response and recovery efforts. There are a growing number of tools available for use in post-event damage assessment. This seminar will discuss these emerging tools and datasets. It will discuss which tools are available for damage assessment of which systems, as well as present detailed analyses of datasets by key features including coverage, resolution, precision, and data availability considering both data collection and data processing times. I will also discuss the importance of considering the spatial and temporal evolution of damage states after an event. Of particular importance is how evolving datasets can be used to provide estimates of damage with increased accuracy and decreased uncertainty as information and knowledge evolves after an event.
The Terrorism Risk Assessment, Modelling and Mitigation Seminar Series (TRAMMSS) is a virtual seminar series focused on technical topics related to terrorism risk assessment, and modelling, including blast modelling and response; IEDs; vehicles as weapons; CBRN; big data for risk assessment, security and screening; and associated mitigation measures.
Speaker
Dr. Iris Tien is Williams Family Associate Professor in the School of Civil and Environmental Engineering at the Georgia Institute of Technology. She joined the faculty in 2014 after receiving her Ph.D. in Civil Systems Engineering from the University of California, Berkeley. Dr. Tien’s research interests are in probabilistic methods for modeling and reliability assessment of civil infrastructure systems. Her research leverages her unique interdisciplinary expertise encompassing traditional topics of civil engineering, sensing and data analytics, stochastic processes, probabilistic risk assessment, and decision making under uncertainty. Dr. Tien’s research has been funded by the National Science Foundation, Department of Homeland Security, U.S. Department of Transportation, and National Institute of Standards and Technology. Her work on interdependent infrastructure systems modeling and analysis has twice won 1st Place Paper Awards in resilient critical infrastructure. She was selected by the National Academy of Engineering to organize the session on Resilient and Reliable Infrastructure at the U.S. Frontiers of Engineering Symposium; and speak on Community Resilience at the National Academies Frontiers of Science, Engineering, and Medicine Symposium. Dr. Tien was awarded the prestigious Early Achievement Research Prize by the International Association for Structural Safety and Reliability (IASSAR), and her published work has been recognized as Editor’s Choice Selection Papers in multiple journals, including the ASCE Journal of Infrastructure Systems, ASCE Journal of Water Resources Planning and Management, and the ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems.
