Today’s design engineers who work with transportation agencies are asked to develop more complex and complete designs for culverts than ever before. Evolving requirements now often include aquatic organism passage and aspects of long-term channel stability. This course will provide participants the knowledge necessary to design a culvert considering issues of peak flow, aquatic organism passage, and local policies of importance.
Participants are required to bring their own laptop computer to the workshop.
At the end of the seminar the participants should be able to calculate design discharge for stream crossings and design a culvert considering headwater limitations, velocity restrictions, local policies, and aquatic organism passage.

Dr. Rollin H. Hotchkiss is a professor in Civil and Environmental Engineering at Brigham Young University (BYU). In addition to his 15 years at BYU, Dr. Hotchkiss worked 7 years at Washington State University as Director of the Albrook Hydraulics Laboratory and 6 years at the University of Nebraska-Lincoln. He is a registered professional engineer in Nebraska and holds an advanced registration as a Diplomat of the American Academy of Water Resources Engineers.
His major research areas include mitigating reservoir sedimentation and the interdisciplinary issue of providing passage for fish through culverts and at dams. Dr. Hotchkiss has advised more than 70 graduate students and has authored or co-authored more than 100 conference papers and project reports and 40 refereed journal papers.
He is past President of the American Society of Civil Engineers’ Environmental and Water Resources Institute (EWRI) and currently serves on the Environmental Advisory Board for the Chief of the U.S. Army Corps of Engineers.
Dr. Hotchkiss has taught short courses on culvert design in Canada, Panama, and more than 25 states in the United States to hundreds of practitioners.
