IIHR—Hydroscience and Engineering at the University of Iowa is the oldest academic research center in the United States focused on hydraulic engineering and fluid mechanics. With over a century of experience, IIHR has played a key role in advancing the science and application of hydraulics in major civil infrastructure projects worldwide. This webinar will provide a brief overview of IIHR’s research mission, technical capabilities, and areas of collaboration, followed by a focused look at our work on the Ellicott City flood mitigation project. Dr. Troy Lyons, Associate Director of IIHR, led the hydraulic modeling efforts for the project. His expertise spans hydraulic structures, urban stormwater systems, drop shafts, and deep tunnels—critical elements in complex flood resilience and conveyance design.
