Rivers are among the most geomorphically active agents of Earth’s surface. Through the processes of erosion and deposition, changes in channels impose migration in single-threaded meandering channels and multi-threaded braided and anabranching rivers. Reach-scale channel reconfigurations occur on a consistent pace through migration, but also occur rapidly through cutoffs, bifurcations, and avulsions, which dramatically alter local energy gradients, sediment erosion and deposition, and channel migration rates. On larger spatial scales, river networks are also dynamic, they reorganize over timescales from decades to millions of years through processes such as drainage divide migration, river capture, and avulsion. This session invites contributions examining river reorganization across spatial and temporal scales. We welcome studies investigating varying planform dynamics, hydrologic connectivity and variability within channel systems, sedimentation, effects of the changing climate, interactions between fluvial processes, ecosystem dynamics, and climate change, and that identify how these changes impact landscape evolution and biodiversity.
