VELOCITY PROFILES AND DISPERSION IN ESTUARINE FLOW

The dispersion of pollutants in tidal waters is caused by turbulence and the shear effect of oscillatory, density, wind driven and steady flow currents. This investigation examines velocity gradients in an oscillatory system and the effects that these gradients have on the spread of pollutants. Velocity distributions are derived from the equations of motion and a mass balance relationship is used to model the dispersion process. The resulting equations can be used to estimate the spread of pollutants in the uniform density sections of estuaries in which tidal motion is the predominant mechanism of dispersion or combined with equations which represent the influence of density, wind driven or steady flow currents.
