Session ID#: 18067

Session Description:
In watersheds throughout the world, physical and biological processes that produce complex channel, riparian and floodplain habitats have been disrupted, resulting in altered riverine ecosystems. Emerging restoration practices focus on restoring key processes (e.g., large floods, floodplain connectivity, sediment transport continuity, wood recruitment, species reintroductions) to restore the form and function of rivers. This session explores the physical and biological processes that produce diverse river and floodplain ecosystems, how human activities have altered those processes, and how restoring them can improve ecosystem condition and function. We seek focused, process-based presentations highlighting both the mechanics of complex processes and examples of recreating biophysical interactions to restore river functionality across multiple spatial and temporal scales.
