This paper describes the results of a sub task of the Dam Foundation Erosion Study, a cooperative research study by Reclamation, PG&E, Colorado State University, and Western Area Power Administration. Pit 4 Dam is located on the Pit River, in Shasta County, California, about 8 miles northwest of Burney, California. The dam, constructed in 1927, is a composite-type structure, with the right half being a spillway section and the left half a slab-and-buttress structure. This paper describes experiments simulating erosion in the foundation area of the slap portion of the Pit 4 dam. The experiments include collecting data on extents and temporal changes of erosion in the fbundation area of the simulated facility.
