Rivers, Watersheds, and the Landscape

IIHR researchers are addressing issues related to sustainability in the water, energy, and food nexus; improving our understanding and adaptation to climate change; increasing community resilience to natural hazards; and helping equip society with the tools to make informed decisions.

Fluid Mechanics and Structures

Fluid mechanics, the study of fluid behavior at rest and in motion, is at the core of nearly all IIHR research. IIHR uses the basic governing equations of fluid mechanics to investigate a wide range of applications—river flow, atmospheric conditions, renewable energy (e.g., wind and water turbines), ship hydrodynamics, biological systems, and much more.

Health and the Environment

Much of IIHR’s research touches all our lives, affecting human health and well-being in meaningful ways. Studies of biofluids, environmental contaminants, vulnerability, and resilience are relevant to each of us. In addition, projects on renewable energy and watersheds help remediate society’s negative environmental impacts, leading to a higher quality, more sustainable life.

Information Systems

Beginning with the innovative Iowa Flood Information System (IFIS) in 2011 (updated in 2026), IIHR has made online public access to research data the standard for its major research initiatives. IIHR has developed online data access systems for water quality information, flood mitigation projects, well-driller information, and more. These platforms provide emergency managers, decision-makers, and the public with accurate and reliable data.

Serving Iowans

From flood to drought, surface water to groundwater, IIHR is helping Iowans understand and manage water resource challenges to ensure a livable and sustainable future.

Healthy Iowa: Environmental Science, Public Health Data, and the Law

Monday, November 9, 2026 12:30pm to 2:00pm
Boyd Law Building

Environmental contaminants, from PFAS and pesticides to emerging contaminants that may not yet be fully understood, raise complicated questions for communities: What are we being exposed to? What are the potential health effects? How do we know when there is a problem? Who is responsible? And what can communities and individuals do when contamination is discovered?

This public-facing panel will bring together experts in science, public health, and environmental law to explore those questions and...
