Improving the design of large wood for streambank stabilization

<jats:p>The Engineering With Nature® (EWN®) program provided research and development funding to develop a module within the Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic design tool that can calculate the stability of large wood for river restoration designs. To properly scope the tool, expert opinions were gathered from a group of highly experienced engineers who regularly use large wood in streambank stabilization projects. A premeeting survey was distributed in preparation for a one-day workshop that was held on 21 February 2023 at the US Army Corps of Engineers (USACE)–Seattle District. This EWN technical note summarizes the feedback that was received and the outcome of the workshop.</jats:p>
