UI engineer receives $466,980 grant to build North Carolina research equipment

Pete Haug, registered professional civil engineer and mechanical shop supervisor at the University of Iowa College of Engineering's renowned IIHR-Hydroscience & Engineering research center, has received a $466,980 grant from the University of North Carolina at Chapel Hill to design water research equipment for UNC.

The nine-month project, which began in September at the UI Hydraulics Model Annex, involves the design, construction and installation of a modular wave basin and tilting flume.

"The wave basin and tilting flume will be used for coastal hydrodynamic studies such as density currents, wave propagation along beaches, and freshwater-saltwater mixing layers," Haug said. "The IIHR-Hydroscience & Engineering laboratories in Iowa City maintain similar basins and flumes, though ours are not capable of handling corrosive saltwater environments. To handle the corrosive saltwater and wave basin pressures, IIHR plans to construct the flume with stainless steel and thick aquarium glass panels."

Haug said that the UNC water research equipment will differ from IIHR equipment not only in its ability to handle saltwater, but also in the manner of its construction. IIHR's basins and flumes are generally built in place, but the UNC wave basin and flume will be constructed in Iowa City, disassembled into manageable sizes, transported to North Carolina via semi-trailer truck, carried down a freight elevator, and installed in a sub-basement beneath UNC's new Chapman Hall, according to Haug.

At its largest points, the UNC wave basin will be 40 meters long, 3 meters high, and 3 meters wide. The separate tilting flume is approximately 10 meters long, 1.75 meters wide, and 1 meter deep.

Plans call for the wave basin and flume to be installed on the UNC campus in summer 2009.

IIHR is one of the world's premier and oldest fluids research and engineering laboratories. Students and visitors from around the world come to IIHR to study, conduct research and to carry acquired expertise back to their home countries.
