Abstract: In July 2005 the EWRI/ASCE Task Committee on Sediment Dynamics Post Dam Removal brought together many national experts, both in research and practice, on the specific topic of sediment dynamics post dam removal. Twenty-five papers were presented regarding the state-of-the-science and state-of-the-practice in considering sediment remobilization and channel dynamics post dam removal. Additional papers reflecting current approaches on this topic were then added to the initial 25 and compiled into a monograph. Authors included representation from federal agencies, universities, consulting firms, environmental non-profit organizations, and academic research laboratories, as well as state agencies; including engineers, geomorphologists, academic researchers, hydraulic/hydrologic modelers, model developers, ecologists, and fisheries biologists. The papers reflect the large regional and project-specific variety relating to this topic. Subjects covered include physical models, numerical simulations, specific case studies, decision-making processes, individual dam issues, geomorphic changes, channel bed evolution, downstream sediment transport, ecological implications, lessons learned from case studies, and sediment quality. Further, these papers encompass the wide variety in sediment composition, hydrologic region, and project scale. This paper will summarize the findings in the monograph papers, and therefore the many national ongoing efforts and the state-of-the-science/practice in the field of sedimentation as it relates to river dynamics post dam removal.
