Quantifying Resilience: Coastal Structures and Nourished Beaches
Publication: Coastal Structures and Solutions to Coastal Disasters 2015: Resilient Coastal Communities
ABSTRACT
Resilience is a ubiquitous term in the aftermath of hurricanes Isabel, Katrina, and Sandy. Nevertheless, there have been few attempts to quantify resilience in coastal engineering practice. This paper addresses this gap and presents a method to quantify resilience. The basic concept is to integrate: (1) Structure/Beach damage during a storm and (2) Time needed to recover from storm damage. Both items need to be summed over a range of storm return periods. The above integration provides a single numerical score that can be used to rank alternative coastal structure and beach nourishment plans. The methodology is based on the work of Chang and Shinozuka (2004) in the context of earthquake engineering and has been recently advanced by Schultz and Smith in preparation (2015).

ACKNOWLEDGMENT
The author appreciates the discussions with Martin Shultz and Julie Rosati, both of USACE/ERDC. The concept of applying the Chang and Shinozuka (2004) engineering resiliency owes to Dr. Martin Schultz.
