IIHR—Hydroscience and Engineering is an internationally renowned laboratory where researchers are solving some of our world's greatest fluids-related challenges.
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, 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 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.
