Recent environmental research conducted at the University of Iowa found that as climate change continues to progress, Iowa and the greater Midwestern region will become more prone to extreme flooding events.

Some climate experts and activist groups have expressed concerns about the findings of the research, which reaffirms the potential consequences of failing to address climate change.

Gabriele Villarini, Director IIHR – Hydroscience and Engineering (formerly the Iowa Institute of Hydraulic Research), said extreme flooding events in Iowa have increased in frequency within the past few decades.

Villarini added that findings from the research, which he was involved in, help demonstrate the local and more tangible impacts of climate change.

“What this work does is add to the existing scientific literature,” Villarini said. “It brings the implications of climate change to a more regional perspective.”

Iowa City Assistant City Manager Ashley Monroe expressed her concerns about such weather events, specifically when it comes to Iowa’s infrastructure.

“We still are seeing the very real impacts of the 2008 flood in effect over ten years later, because of the level of damage to university and city infrastructure,” Monroe said. “We must continue to be smart about how we design and locate facilities and housing that will stand up to increased rainfall and extreme weather.”

The 2008 flood destroyed many UI buildings, including the Adler Journalism Building, Hancher Auditorium, Mayflower Residence Hall, and the Stanley Museum of Art.

Monroe added that the city has already taken certain actions to help protect local infrastructure from flooding events.

“The city has purchased flooded properties and expanded park land, ensuring that areas within the 100- and 500-year floodplains avoid further development,” Monroe said.

Floodplains are a way of measuring the likelihood that a certain plot of land will flood in any given year. For a 100-year floodplain, there is a one in 100 chance that the plot of land will flood in a given year. For a 500-year floodplain, there is a one in 500 chance of the land flooding in the same time period.

Concerns related to flooding in Iowa are not a recent development, however. The Iowa Flood Center was established as a branch of the IIHR organization in 2009, following the 2008 flood disaster in eastern Iowa in order to help Iowans mitigate the impacts of such events in the future.

Communications Specialist at the Iowa Flood Center Breanna Shea said while there are no current projections for major flooding events in Iowa this season, the Iowa Flood Center is constantly monitoring data and expanding technology to help keep Iowans prepared.

“Within the last year, we’ve added 35 additional stream sensors to our statewide stream sensor network,” Shea said. “Those measure river levels in real-time every 15 minutes and then they communicate and visualize that data to the Iowa Flood Information System platform.”

Shea said it is important for Iowans to remain well-informed, because even simple weather developments can change the flood outlook in Iowa this season.

“We always want Iowans to be prepared for anything,” Shea said. “Changes in precipitation and a couple of days of heavy rainfall could make a big difference. So, it’s always good for us to be doing that outreach and education.”
