Introduction to Dam Decommissioning: On-Demand
Speaker: Paul G. Schweiger, P.E., Vice President, Gannett Fleming, Inc.
PDHs: This webinar is eligible for 2 PDH credits.
As dams deteriorate, or as their purpose and benefits diminish, there may come a time when the appropriate action is to decommission the dam. For some dams, this can be a very simple, rapid and inexpensive undertaking. For other dams, it can be a very complex and costly process, requiring years to accomplish. The purpose of this webinar is to provide an overview of recent trends in dam decommissioning in the United States with an emphasis on the engineering and design aspects of dam decommissioning. Distinctions will be made between decommissioning run-of-the-river dams versus traditional storage dams, high and significant hazard dams versus low hazard dams, concrete and masonry dams versus embankment dams, and large dams versus small dams. Reservoir sediment issues and management strategies will also be presented and discussed. The webinar will include many examples of decommissioned dams and provide participants with key references and best practice documents for dam decommissioning.
