Abstract: A research effort was initiated in 1983 by the Bureau of Reclamation to gain insight in the development of cost-effective modifications to small embankment dams which would enable them to withstand overtopping. A small flume, 3 ft wide by 4 ft high by 30 ft, was constructed to contain the 2. 12-ft-high soil test embankments and flow. The nature and modes of erosion of the small embankments were observed during overtopping flow.
