Abstract : An analytic solution of the unsteady three dimensional advection- dispersion equation is developed. The solution
depicts the concentration distribution for a non-conservative contaminant or substance injected as a pulse into a stream by a
diffuser installed normal to the stream bank with a certain area. The stream has constant mean velocity and relatively large
discharge in comparison to the contaminant source discharge. The solution is developed using FourierSeries and Laplace
transforms. The profile of concentration in the stream due to such contaminant disposal is developed in terms of
Complementary Error function, Exponential and Trigonometric series. The location variations of the diffuser across the
stream are examined. The effects of time period (during and after pulsing) on the concentration profiles across, along and
normal to the stream are determined. The paper also represents the effects of decay coefficient as well as many hydraulic and
geometric parameters on the variation of mixing patterns.
