Stream ecology, Water quality
Two existing stream dispersion computer models were applied to a hypothetical stream to analyze mixing zone requirements due to point and non-point discharges. Mixing zone curves were developed to define acceptable and unacceptable regions of stream response for stead-state and transient conditions. The impact on these regions due to varying quantitative and qualitative characteristics of the stream and waste discharges were investigated. In addition, a sensitivity analysis was conducted on the response of a transient one-dimensional stream dispersion model. A logarithmic linear regression analysis, relating the number of time increments specified to a dimensionless hydrograph shape factor for known storm water and combined events, gave correlation coefficients of 0.915 and0.925 for 94% and 98% model accuracies, respectively.
