IIHR Director Gabriele Villarini will introduce IIHR’s history of research and engineering on the Mississippi River. Following this introduction, Augustana College Research Associate Matthew Fockler will share his project, Two Mississippi — a historical and geographic investigation of the Upper Mississippi River since its greatest manmade alteration, the 9-Foot Channel Project (Researched by IIHR).

To attend the event you must register for a spot. Please see the link at the bottom of the page.

The UI Pentacrest Museums welcome the University of Iowa’s IIHR—Hydroscience and Engineering for a two-part virtual program focusing on IIHR’s history of research and engineering on the Mississippi River and an overview of current watershed initiatives that the 101-year-old institute is leading today. These educational programs are in conjunction with IIHR’s centennial exhibition, A River Flowed Through It: Iowa’s Legacy in Fluid Mechanics, on display through December 2021 at the Old Capitol Museum of the University of Iowa campus and also available as a virtual exhibit.

IIHR’s work on the Mississippi River dates to the 1920s, when researchers set out to measure the flow of the river just upstream of the Keokuk Dam (now part of Lock and Dam No. 19) at Keokuk, Iowa. IIHR Director Floyd Nagler also modeled the dam’s spillways for the Mississippi River Power Company.

In the late ’20s, research interests on the Mississippi River expanded to flood control and the impacts of agriculture on the basin. During this time, the U.S. Army of Corps of Engineers, working with Nagler and others at IIHR, began the 9-Foot Channel Project, supported by an act of Congress. The goal was to make the river deeper and wider to create more safe, reliable passageways for commercial navigation. The project became the system of locks and dams we’re familiar with today. The unexpected impacts of the project are also still being felt.
