With the growing concern over adverse environmental impacts of dams on ecosystems and fish populations, the number of dam removals is rapidly increasing. Dams alter ecology, block fish passage, increase downstream scour, and displace residents, and dam removal is now a common solution. Concerns have arisen regarding the behavior of stored sediment and overall stream geomorphology when the dam is removed. Because large amounts of sediment have collected behind many dams, the issue of what will happen to the impounded sediment if the dam is removed is of critical importance. This monograph provides guidance and documentation of numerical and physical modeling and field experience regarding dam removal and its modeling. It will be a valuable aid to watershed and river agencies and their consultants, as well as to researchers.
