One Concern reviews our cutting-edge research with leaders in the fields of disaster science, data science, engineering, and water resources through regular meetings with our Technical Working Group. We recently convened a meeting to review One Concern’s latest infrastructure, flood and seismic models, inclusive of downtime and recovery calculations.

Our flood models are unique in that they combine riverine, coastal, and urban flooding models, including an alert-driven and scalable operational forecast system, and enable scalable inundation modeling at national scale, which allows users to consider possible flood impacts regionally rather than throughout a large area. During the Technical Working Group meeting, our team presented validations of our models against gauge observation as well as on real life flooding events.

The One Concern team also presented our latest resilience modeling research including the machine learning model for estimating building damage in Japan as well as new vulnerability and recovery estimation tools. Lastly, the team presented their methodology for estimating downtime of people, ports, airports, roads, and bridges and utilized Los Angeles as a case study to demonstrate time to recovery corresponding to hazard maps with a variety of return periods.

As we continue to research and develop new products to enable a resilient future globally, we are grateful for the insights our Technical Working Group offers us to ensure that we not only leverage the latest in disaster science, but that we remain leaders in the field of disaster mitigation.

This year’s technical working group meetings were held on the 14th-17th and 22nd of June. Advisors in attendance included Jeremy Bricker (Associate Professor, University of Michigan, TU Delft), Nobuhito Mori (Professor, Disaster Prevention Research Institute, Kyoto University), Joseph Zhang (Research Professor, Virginia Institute of Marine Science),Jamie Padgett (Professor, Rice University), Greg Deierlein (Director, John A. Blume Earthquake Engineering Center, Stanford University), and Roger Borcherdt (Scientist Emeritus, Earthquake Science Center, United States Geological Survey).

The Technical Working Group members include:

  • Dr. Jeremy Bricker, Associate Prof., Hydraulic Engineering at TU Delft, and Associate Professor in the Department of Civil and Environmental Engineering at University of Michigan, Ann Arbor, is a hydraulic and coastal engineer focused on the application of fluid mechanics to engineering design.
  • Dr. Nobuhito Mori, Professor, Disaster Prevention Research Institute, Kyoto University, has areas of interest including air-sea interface physics, climate change, the dynamics of wind waves, long waves and tsunamis.
  • Dr. Y. Joseph Zhang, Research Professor, Virginia Institute of Marine Science, has research interests in theoretical and computational geophysical fluid mechanics, nonlinear wave mechanics, complex 3D environmental flows and numerical methods.
  • Dr. Jamie Padgett, Professor, Department of Civil and Environmental Engineering, Rice University. Dr. Padgett’s research focuses on the application of probabilistic methods for risk assessment of infrastructure, including the subsequent quantification of resilience and sustainability. Her work emphasizes structural portfolios such as regional portfolios of bridges or oil storage tanks exposed to multiple hazards, including earthquakes, hurricanes, or aging and deterioration.
  • Dr. Gregory G. Deierlein, Director, John A. Blume Earthquake Engineering Center, Stanford University, has done transformative research which has influenced the development of national codes and guidelines related to stability and collapse of buildings and other structures.
  • Dr. Roger Borcherdt, Scientist Emeritus, Earthquake Science Center, United States Geological Survey, has a career marked with “exceptional scientific contributions in the fields of seismology and engineering seismology, extraordinarily broad in scope” as noted on the Presidential Distinguished Service Award he received in 2010 as the highest honor of the U.S. Department of Interior.
