Bio

Mr. Corum serves as a Senior Hydraulic Engineer for the Seattle District, USACE focused on numerical modeling and ecosystem restoration (planning, design, construction, monitoring), joining the Corps in 2001. He is a Registered Professional Civil Engineer in the State of Washington, has completed the Corps’ Leadership Development Program level 1 and 2 courses, and is ATR certified for hydraulic engineering and ecosystem restoration (most recently completed review of Engineer Manual 1110-2-4000). From 2020 to present Mr. Corum has served on the Corps’ Committee on River Engineering. Mr. Corum also serves on the Kootenai River Peer Review Advisory Team, which is a multi-discipline interagency stakeholder group advising on major ecosystem recovery efforts in the valley.  Mr. Corum is also a technical lead for civil works ecosystem restoration and flood damage reduction projects. His project portfolio spans from Alaska to Brazil and is centered in the Pacific Northwest (WA, ID, OR, MT) on use of numerical modeling, natural processes and NNBF to help with aquatic ecosystem rehabilitation efforts. Mr. Corum is a recognized USACE SME for engineering with large wood and has developed several innovative techniques for applying large wood and natural processes to address traditional engineering challenges. Since 2005 Mr. Corum has designed engineered logjams and woody revetments for the Green River, Cedar River, Skokomish River, Duckabush River, Dungeness River, Skagit River, Yakima River and Kootenai River and several smaller tributaries. Other notable projects include supporting the National Park Service with removal of the Elwha River dams (hydraulic engineer and project manager); lead hydraulic engineer supporting the Green River gravel and large wood nourishment project; technical lead for investigation of woody debris management alternatives for public ports on the Madeira River (Brazil) in support to Mobile District; lead designer of the Kootenai River/Dunn Creek large wood habitat restoration project and co-designer of the Skagit River project, both featured in the EWN Atlas Vol 1. Mr. Corum relishes projects on “messy” rivers that inspire innovation and personal growth. He also enjoys the occasional watercolor painting and grind through the skatepark when he’s not tending to his family and cats.
