We hosted a session at our James Street Laboratory for the most recent Discover Your University, and had a wonderful time showing University of Iowa staff some of the work we're doing!

Staff from multiple departments joined us to check out one of our latest physical modeling projects of a stormwater system with four drop shafts.

They learned about IIHR Engineering Services' modeling work and why physical modeling is an important step in the engineering process. Thanks to all of the University employees who took time out of their day to come check us out!

For visitors to Iowa, a field trip to a working farm can be quite an adventure.

That was the case when IIHR—Hydroscience and Engineering took about 25 visitors from around the country on a visit the Schott Family Farm south of Iowa City. The Schott family's century old farm operation now includes sons and daughters-in-law taking key management roles as the family begins to pass the baton on day-to-day operations.

Their farm includes corn and soybean production, incorporating cover crops and no-till farming as protective land-use practices. They are also exploring implementation of edge-of-field practices, such as saturated buffers and bioreactors, to boost their conservation practices.

A big thank you goes out to the Schott family for the warm welcome and the valuable exchange of information and ideas!

Why should we monitor what’s in our water? Marty St. Clair, former chemistry professor at Coe College, and a current IIHR—Hydroscience and Engineering and Center for Health Effects of Environmental Contamination (CHEEC) research scientist, spoke to that question and many others in his presentation to Greater Iowa City, Inc. Community Leadership Program participants on May 8 at the Johnson County, Iowa Historic Poor Farm.

His topic, “Tracking What Matters: Environmental Monitoring Across Iowa’s Waters and Communities,” addressed concerns that many Iowans have about water quality, nitrate, “forever chemicals,” pesticides, and more.

Despite the serious topic, St. Clair managed to keep the audience engaged and entertained, proving why his chemistry students said he made class fun. St. Clair is part of the IIHR—Hydroscience and Engineering and the Center for Health Effects of Environmental Contamination.

IIHR was proud to welcome partners from the Cooperative Institute for Research to Operations in Hydrology (CIROH), based at the University of Alabama, for a collaborative exchange focused on water quality challenges and opportunities to strengthen national water quality forecasting efforts.

Discussions showcased IIHR’s leadership of the nation’s largest real-time, continuous water quality monitoring network and highlighted the essential role of community partnerships in driving impact. By building on this experience, IIHR and CIROH are working together to accelerate the transition of water quality research into operational tools that can benefit communities across the country.

Partners traveled from as far as Hawaii, Vermont, Colorado, and Utah to participate in meetings, facility tours, and in-depth conversations. The visit concluded with a tour of Schott Family Farms, offering valuable insight into a multi-generational, production-scale farming operation and how research can better support farmers and land stewards.

Thank you to our CIROH partners for making the trip and contributing to meaningful collaboration. We look forward to continuing this important work together!

Forecasting flash flooding across five countries, multiple time zones, three languages, and under an extremely tight schedule might sound like a research nightmare, but not to the Iowa Flood Center's Humberto Vergara, an assistant professor in the University of Iowa College of Engineering and IIHR research engineer.

"It's exciting," Vergara says. With a $1.2 million grant from the World Meteorological Organization, Vergara and his Advanced Hydrology and Warning Applications team are working to make early flood warning systems a reality in Comoros (an island off the east coast of Africa), Haiti, Barbados, Guatemala, and Antigua and Barbuda — and perhaps beyond, given time.

“I would like to continue expanding some of these same efforts to other countries,” Vergara says.

Congratulations to Larry Weber, director of IIHR and the Iowa Flood Center, on being selected as an Iowa Water Warrior by the Iowa Storm Water Education Partnership.

The Water Warrior Award recognizes individuals who have made significant contributions to stormwater management across the state. Weber was honored at the ISTORM Conference at the University of Northern Iowa, where he also delivered a keynote address.

This recognition reflects Weber’s longstanding commitment to protecting Iowa’s waterways and advancing effective stormwater management practices. Join us in congratulating him on this remarkable achievement! 👏
