Generalized dispersion theory is used to study the unsteady dispersion of pollutants in open-channel flow. It is shown that the dispersion equation has time dependent coefficients and that it applies only to initial value problems such as the concentration distribution created by an instantaneous source.

A superposition integral is used to study the distribution of BOD from a continuous source. It is shown that the usual constant coefficient dispersion model can lead to significant errors when applied to continuous source problems, especially when one is interested in concentration distributions near the source.
