The Institute for Resilient Infrastructure Systems advances the integration of natural and conventional infrastructure systems to strengthen society's long term resilience to flooding, sea level rise, drought and other disruptions
Through collaborative partnerships, interdisciplinary expertise and research innovations, we empower communities and businesses to discover wise infrastructure solutions that deliver a broad array of social, economic and environmental benefits.


With an interdisciplinary team that spans over ten University of Georgia Schools and colleges, IRIS projects are as diverse as the people who conduct them. Examples of our current projects are below:

Using climate data provided by AT&T via the U.S. Department of Energy’s Argonne National Laboratory, the Institute for Resilient Infrastructure Systems examined how flooding in Athens, Georgia, impacts communities differently. The study found that flooding impacts low-income and minority communities to a much more severe extent than other areas of the town–Black, Hispanic and low-income communities faced a flood risk anywhere from 38% to 185% higher than the average risk. 

Institute for Resilient Infrastructure Systems researcher Dr. Matthew V. Bilskie, assistant professor in the College of Engineering, is working to understand how natural- and nature-based infrastructure can mitigate flooding and reduce wave energy in coastal communities.

IRIS and partners are streamlining the consultation process involving imperiled aquatic species potentially affected by GDOT construction projects that affect freshwater ecosystems. A streamlined consultation process will ensure that species receive protections that are most important to their life stage and sensitivities.


IRIS selected to develop innovative approaches for resiliency at military installations

The Institute for Resilient Infrastructure Systems (IRIS) at the University of Georgia was selected by the U.S. Army Corps of Engineers to develop innovative approaches for collaborating with U.S. military installations and their adjacent communities to increase resilience through Engineering With Nature and natural infrastructure solutions. With a team whose expertise cuts across engineering, environmental …

Story Map: At what scale does natural infrastructure have the biggest impact on community resilience?

As part of the N-EWN collaboration, IRIS researcher Dr. Matt Bilskie (Assistant Professor in the College of Engineering, University of Georgia), along with his research partner with the U.S. Army Corps of Engineers, Dr. Amanda Tritinger and their team of collaborators set out to find out. It can be difficult to assess the real-world impacts …


The Network for Engineering with Nature (N-EWN) invites you to join us for The N-EWN Knowledge Series: A Continuing Education Series about Engineering with Nature. The next webinar will be held on Tuesday, September 21 at 12:30 EST at which Brook Herman (PhD, USACE-ERDC) will be sharing about characterizing USACE EWN projects and progress on …
