Nakato Receives National Engineering Award

Tatsuaki Nakato, research engineer at IIHR -- Hydroscience & Engineering and director of the Lucille A. Carver Mississippi Riverside Environmental Research Station, has been awarded the 2006 Hydraulic Structures Medal by the American Society of Civil Engineers.

The award, given for "significant contributions to the advancement of the art and science of hydraulic engineering as applied to hydraulic structures," was presented during the 2006 World Environmental & Water Resources Congress held May 25 in Omaha, Neb.

Nakato has published five journal papers, 20 conference papers and 42 IIHR technical reports on related pump and turbine-intake investigations and investigated emergency core-cooling systems for many U.S. nuclear power plants. In particular, he helped the staff of Laguna Verde nuclear power plant in Mexico to operate their condenser cooling systems smoothly. His laboratory and field investigations also include municipal water supply systems and hydropower turbine-intake designs. In addition, he model-tested the Five-in-One dam hydropower plant located under the I-380 Bridge in Cedar Rapids.

Using IIHR's Oakdale Annex facility, he is currently conducting two laboratory studies of the Croton pumping station project, a new water treatment plant at the Mosholu site in the Bronx of New York City. The primary objective of the studies is to find hydraulically objectionable features, such as formation of free-surface and sub-surface vortices that would be detrimental to satisfactory pump operations, and develop design modification solutions using scaled, physical hydraulic models.

Nakato, who began his career in 1975 working on hydraulic model studies for the U.S. Army Corps of Engineers' Lake Chico (Arkansas) pumping station project along the Mississippi River, later inspired the creation of the research station, which serves as a laboratory where biologists, hydrologists, and other scientists -- as well as elementary school, high school, and college students -- study the extremely complex Mississippi River ecosystem.

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