IIHR–Hydroscience & Engineering at the University of Iowa is an internationally renowned laboratory where researchers are solving some of our world’s greatest fluids-related challenges. IIHR engineers build small-scale models of projects in their warehouse-sized facilities, ensuring through design and testing that everything works exactly as it should before the project is built.

In this photo gallery by Office of Strategic Communication photographer Tim Schoon, IIHR engineers designed and built scale models of a complex water-retention and storage system for municipal, agricultural, and other major water users in eastern Colorado, where water supply can fluctuate. IIHR engineers also are testing the efficacy and efficiency of a new pump station that will be added to the Cedar Rapids Water Pollution Control Facilities on the southeast side of that city.
