As part of the ongoing Research Seminars series, the Hatfield Marine Science Center (HMSC) will be hosting Dr. Daniel Cox, a CH2M Hill Professor in Civil Engineering at Oregon State University to discuss his work on community resilience to coastal hazards, including tsunami and hurricane surge and waves inundation in the built and natural environments. His presentation will take place on Thursday, Oct. 27, at 3:30 p.m.

About the talk:

“A new method to evaluate the regional and local resilience of infrastructure networks following disruptions from natural hazards is presented. The regional resilience relates to the a community’s ability to access the larger (state-wide) network, and the local resilience relates to the connectivity within the boundaries of a community. This framework is applied to a road and highway transportation network disrupted by ground shaking and inundation under a Cascadia Subduction Zone earthquake and tsunami scenario. The regional network extents encompass the entire Oregon coast to the I5 corridor. Embedded within this regional network are 18 local networks associated with coastal communities. Regional and local connectivity indexes are defined to identify the initial damage and then track the post-disaster recovery of the transportation network. The study identifies attributes that lead to a regionally or locally resilient network and highlight the importance of considering local infrastructure networks embedded within larger regional networks. For example, we shown that without regional considerations, the time to recover may be severely underpredicted by conventional approaches. The methodology is further used to demonstrate how mitigation options impact the transportation network’s resilience. The importance of strategically considering mitigation options is emphasized as some communities see significant reductions in time to recover, whereas others see little to no improvement.”

These talks are delivered in a hybrid fashion. The event is free, and all are welcome to attend in person in the auditorium of the Gladys Valley Marine Studies Building at the HMSC (2030 S.E. Marine Science Dr).  You can also attend online. Register here to attend remotely via Zoom.
