William J. Rahmeyer

Emeritus Professor of Civil and Environmental Engineering at Utah State University

For 31 years Mr. Rahmeyer was on the faculty at USU, and for 10 years he was on the research faculty at Colorado State University. Mr. Rahmeyer is the past department head of Civil and Environmental Engineering at USU as well as the senior professor of the Hydraulics and Fluid Mechanics program of the Utah Water Research Laboratory. He also served at USU as the Director of the Hydro Composite Modeling Program. He was also the division head of Water Engineering, the interim division head of both the Structures Division and the Transportation Division, he also served as the Undergraduate Curriculum Division Head. He is currently a part time senior associate for Ayres and Associates in Fort Collins, Colorado, where his primary role is to conduct national workshops in hydraulics, culvert flow, and urban drainage for the National Hydraulic Institute of FWHA.
