After returning to the States, Margaret and Irene started at the University of Iowa. They were among the first women to graduate from the College of Engineering and both earned degrees in Civil Engineering in February of 1947. Still working for the Army Corps of Engineers, Petersen moved to Vicksburg, Mississippi, where she worked on the Mississippi Basin Model. She returned to the University a few years later and earn an M.S. in Mechanics and Hydraulics in 1953. She would remain with the Army Corps of Engineers for many years, moving around the country on different assignments, including projects on the Mississippi, Missouri, and Arkansas Rivers. 

In 1980, Petersen joined the faculty of Arizona State University as a visiting associate professor in the Department of Civil Engineering and Engineering Mechanics. During her time there she worked to develop several graduate courses, and wrote the textbook River Engineering. Petersen was appointed as an Emerita Associate Professor in 1991, but did not completely retire from teaching until 1997. Throughout her career she received many awards and recognitions including the American Society of Civil Engineers’ Hunter Rouse Hydraulic Engineering Award and the Environmental and Water Resources Institute’s first Lifetime Achievement Award.
