Abstract: The paper describes a continuation effort by the first two writers in attempting to obtain a derived distribution for the outflow pollutant mass flexes from a wet detention pond. The derivation was based on assumed probability distributions for the build-up of pollutants on land surfaces; the magnitude of rainfall runoff and the amount of pollutant washoff by runoff. The outflow quantity and quality were computed by using a completely-mixed model for the detention pond. The expected values of the input and outflow masses of pollutants can then be used to estimate long-term average removal efficiency of the detention pond. The results will be useful for the determination of design guideline for wet detention ponds.
