Abstract Mine tailings are commonly disposed of in slurry form by subaerial deposition from a pipeline. Coarse mine wastes may be combined with the tailings. At discharge points along the pipeline, the slurry forms sloping beaches whose profiles have a direct bearing on the volume of tailings that can be stored in a given impoundment. The profiles of such beaches are described well by both a power law equation and an exponential equation that incorporate different profile concavity parameters. These two equations, which have been compared previously on the basis of very limited data, are re-examined here on the basis of a much-expanded data set. The exponential equation, which has a theoretical basis, fits the profiles of most beaches slightly better than the empirical power law equation. On average, it gives slightly higher estimates for the volume of tailings that can be stored in a given impoundment. A simple method of conversion from -one profile equation to the other is described.
