For more than four decades, the INTERCOH conference has been at the forefront of tackling theoretical and applied cohesive sediments problems. It serves as the premier international platform for scientists and engineers working to understand cohesive sediment properties and dynamics in both natural and man-made environments via laboratory experiments, field observation, and numerical modeling. The 18th conference will be held between September 8-11, 2026, in New Orleans, LA at the Tulane River and Coastal Center and the University of New Orleans.
