Leading the Next Generation of Stream Restoration Professionals with Gary Wolff
October, 2024
In leading the next generation of stream restoration professionals, Gary Wolff (Otak Senior Hydraulics Engineer) taught a four-day-course this fall on, “steady open channel flow modeling emphasizing stream restoration applications.” It’s part of a stream restoration certificate program at Portland State University and is something he’s been lending his expertise to for the better part of the past decade.
“I love to teach and mentor young people because I’ve been in the business for over 40 years, and it’s a big benefit to our business and the work we do because it increases its exposure.”
– Gary Wolff, Senior Hydraulics Engineer
As a member of our environmental team, Gary has worked on countless projects aimed at restoring streams to their natural state, including aquatic habitat and fish passage. A large part of those efforts has centered around being an industry leader in the application of the Hydrologic Engineering Center – River Analysis System (HEC-RAS) hydraulic modeling software, which he provides insight into as part of this program.
What is the Stream Restoration Certificate Program?
Infrastructure development throughout history has often changed riverine systems from their natural state. Consequently, negative impacts to the natural environment, property, and habitat have been a common result. With growing knowledge around these impacts, efforts are increasingly being made to restore streams to their more natural state, adding resilience to both the environment and surrounding communities.
Co-sponsored by Portland State University and River Restoration Northwest, the Stream Restoration Certificate program positions prospective environmental engineers to better design future stream restoration projects. The ability to model the river and stream systems as part of these projects is a significant piece of that puzzle, and it’s the focus of Gary’s course. As an introduction to the one-dimensional capabilities of the HEC-RAS software, Gary’s course gives river restoration practitioners with backgrounds in geoscience, the life sciences, and engineering the ability to make reliable interpretations of the outputs from these models. Designed as a hands-on experience with the software, it covers modeling for a variety of situations commonly encountered when restoring rivers. This includes a focus on hydraulic modeling of streams with added habitat features (e.g. large wood, boulders), as well as floodplain permitting applications.
