The goal of this study was to provide a rational basis for selecting a sediment control system for surface mine regions that would minimize the chance of exceeding effluent standards set by regulatory agencies for total sediment yield. A probabilistic model to predict storm sediment yield and sediment yield over the lifetime of the mining operation was developed. Probability distributions of sediment yield were determined by coupling probabilistic models of rainfall amount, duration, and time between storms with a deterministic event-based model of the sediment yield process. Using probabilistic analysis procedures and a simulation approach sediment yield probability, distributions were determined for individual storm events and for the lifetime of the mining operation.
