Abstract : Non-uniform flow is a flow in which the velocity at any given time changes from point to point along a streamline. In estuaries, such flows result from the cross-sectional area increasing in the downstream direction. A solution to the convective-diffusion equation for this type of estuary is obtained in terms of the estuarine geometry and the longitudinal diffusion coefficient. The model is applied to the results of two dye tracer experiments carried out in the upper Patuxent River during August 1969 from which the longitudinal dispersion coefficients were quantitated. The concept of a flushing velocity for an estuary is developed and defined. (Author)
