I am a lead bridge hydraulics engineer. Before entering private practice in 1981, I gained 20 years of engineering experience with the U.S. Army Corps of Engineers and academic assignments at the U.S. Military Academy, West Point, New York.
Since 1989 I have been principal instructor for Federal Highway Administration (FHWA) projects to develop and present training courses on stream stability and scour at highway bridges. As part of these projects, I am senior author of HEC-20, "Stream Stability at Highway Structures," and HEC-23, "Bridge Scour and Stream Instability Countermeasures." I am also a technical contributor to HEC-18, "Scour at Bridges."
I prepared the Instructor Guide and Participant Workbook that support the National Highway Institute (NHI) Training Course on Stream Stability and Scour at Bridges and managed, scheduled, and participated in the presentation of this course more than 200 times to state departments of transportation. In cooperation with FHWA reviewers, I recently completed extensive revisions of this course and developed NHI's new countermeasure design course. I've received Instructor of Excellence awards from NHI for my teaching work in 2010, 2012, and 2019.
