Going with the Flow
IIHR has been involved in river-related research since the lab's beginnings, with some of its earliest research focused on improving navigation on the Mississippi River. Early experiments capitalized on IIHR's experimental channel, which drew water directly from the adjacent dam on the Iowa River.
Throughout time, IIHR's research portfolio has adapted and evolved to predict and meet changing societal needs. Established centers within IIHR include the Iowa Flood Center (IFC), Iowa Geological Survey, and Iowa Nutrient Research Center that work together to provide direct benefits serving the people of Iowa with robust and reliable information to understand and reduce their risks to floods, droughts, groundwater sustainability, and water quality. This research has far-reaching impacts across communities and individuals, enhanced by studies on environmental contaminants, renewable energy, and watershed management.

Mississippi River Research
LACMRERS (the Lucille A. Carver Mississippi Riverside Environment Research Station) is the first university-owned research and education center on the Upper Mississippi River. Located just north of Muscatine, Iowa, on the Mississippi River, LACMRERS was designed and equipped to support research and education relating to the Mississippi River and large river systems in general.

Research Spotlight: The Iowa Watershed Approach
Leveraging its expertise through the Iowa Flood Center, IIHR has helped bring more than $100 million to the state of Iowa for the Iowa Watershed Approach—a community-led program supported by state and federal partners to develop and implement strategies to mitigate flood damage and increase resilience. Funded by the U.S. Department of Housing and Urban Development, the IWA brought together local, state, and federal partners, empowering them with science-based information to develop long-term watershed management plans and to guide strategic conservation practice implementation efforts that work progressively with agriculture.
The program ended in December 2022 with the construction of more than 800 flood mitigation projects like ponds, terraces, and wetlands and more than $40M invested in nature-based practices. The program has received national attention from other states including North Carolina, Texas, Louisiana, Missouri, and Wisconsin looking to replicate the successful IWA framework. IIHR and IFC continue to be involved in watershed management efforts across Iowa.
