How to Deal with Sediment in Dam Removal

Ms. Jennifer Bountry
Dr. Tim Randle
Bureau of Reclamation Sedimentation and River Hydraulics Group, Denver, CO

Technical guidelines for dam removal have been developed to link the level of reservoir sediment data collection, analysis, and modeling to the level of risk to river-related resources. In this 60-minute webinar, Ms. Bountry and Dr. Randle will present key components of the guidelines. The presentation will include the reservoir data gathering steps; significance of reservoir sediment volume; sediment and dam removal alternatives; sediment analyses and modeling; and uncertainty, monitoring, and adaptive management. Case study examples from small to large dam removals will also be included to demonstrate how the level of sediment investigation can vary, depending on the potential sediment risk to natural resources or infrastructure.

PRESENTER BIOGRAPHIES

Ms. Jennifer Bountry and Dr. Tim Randle are hydraulic engineers at the Bureau of Reclamation Sedimentation and River Hydraulics Group in Denver, Colorado. They have worked on multiple dam removal projects in the western United States, river restoration design and analysis, and reservoir sedimentation issues throughout the world. They have recently published on the Savage Rapids and Elwha Dam removal projects, and led the development of two guidelines on dam removal implementation and sedimentation analysis.
