Although there is an increasing body of literature about the impact of dams on hydrology, the concomitant spatial and temporal response of sediment regime is highly variable within the context of catchment geology, land use, pre-dam sediment supply and transport regime, degree of hydrologic alteration, and dam operation. This session welcomes papers that explore the impact of dams in disrupting longitudinal sediment transport, and thus their influence on sediment budgets, channel morphology, and bed sedimentary dynamics. It is anticipated that papers will address a wide variety of adjustments to impoundments including reservoir sedimentation and delta formation, as well as changes to longitudinal and downstream fining profiles, sediment loads, and downstream sediment sinks. In addition, we look forward to papers that model sediment transport in regulated rivers e.g., related to flushing flows and gravel augmentation. This session will attempt to integrate a wide area of fluvial geomorphology on this topic and to address central issues for management and restoration in regulated rivers worldwide, including socioeconomic issues, especially considering the implementation of the Water Framework Directive in Europe.
