Landlocked Iowa: A surprising hub of amphibious vehicle research

Wednesday, March 6, 2019
An IIHR researcher is working out how an amphibious vehicle can operate in the perplexing surf zone. Hiroyuki Sugiyama, UI associate professor of mechanical engineering, is working on simulating the vehicle when it’s operating on land.
