Impact of Vessel Operations on Navigation Channel Stability and the Broader Environment: Insights from a Workshop Held 4–5 September 2024

Abstract: Vessel operations in the US Army Corps of Engineers (USACE) portfolio of waterways create a range of environmental and navigation challenges. This report documents the proceedings of a workshop highlighting research and development (R&D) on vessel-related navigation channel stability and associated environmental impacts. Across 13 workshop presentations, three major themes emerged to guide future USACE R&D efforts: (1) the need for better data and standardized processing routines, (2) the need for a streamlined modeling framework that can simulate all relevant physical processes for vessel operation, and (3) the need for improved internal and external partnerships to better address vessel-related issues. Addressing these critical knowledge gaps will advance engineering practice associated with vessel operations in USACE waterways.
