This paper summarizes the method that will be used by the Bureau of Reclamation to investigate scour of spillways and dam foundations, and to develop a numerical model to compute the same. In what follows the basis of a unique relationship between the erosive power of water and the ability of earth materials to resist erosion, known as the Erodibility Index Method, is presented. The paper also provides a description of the approach that will be used by the numerical model to calculate the erosive power of plunging, aerated jets. The complimentary paper, Wittler (1995), describes the approach that will be used to investigate the extent of scour of spillways and dam foundations.
