||The Probability Dilution Model provides a screening level methodology for determining the effect of intermittent pollutant discharges on the water quality of streams and rivers. The processes analyzed in the model (urban runoff, streamflow, and water quality) are probabilistic by nature and are treated as such by the model. The method uses a deterministic mass balance approach and accounts for the nature variabilities in the model inputs into the stream. This model is an extremely useful screening level tool for initial planning purposes to help determine problem areas and to screen possible control alternatives. Three methods, the Analytical Derived Distribution Approach, a numerical Gaussian Quadrature method and the Monte Carlo simulation approach, are presented.
