Scope/Content: Abstract: Evaluation of sediment transport dynamics following dam removal usually requires extensive field data, the collection of which requires both resources and time. Certain management decisions with regard to the removal of a dam, however, may be required before the commitment of such resources. Here we present a case study and demonstrate that certain aspects of the sediment transport characteristics following dam removal can be evaluated with very limited information available. The case study in question involves J.C. Boyle, Copco, Copco II, and Iron Gate Dams on the Klamath River, California with an estimated 11.6 million cubic meters (15.2 million cubic yards) of sediment deposit. With a reconnaissance field observation and upon examination of the very limited existing field data, we determined that it is possible to evaluate the potential sediment deposition downstream of the dam following the removal of the dams under the worst-case-scenario assumptions. The evaluation was carried out with the help of DREAM-1, one of the Dam Removal Express Assessment Models developed at Stillwater Sciences, California. Results of the assessment indicate that potential sediment deposition would occur only for a brief period within a few miles downstream of the dam with a maximum thickness of sediment deposition no more than 1.2 m (4 ft).
