Abstract
A theory of the mixing and dispersion of wastes in tidal waters is developed. The resemblance of the final equations to the solution of a diffusion equation is noted, and the frequency and length parameters that control the mixing and dispersion are related to a mixing coefficient. The problem of maximum waste concentration with a continued waste discharge is examined, and it is concluded that for an inherently stable waste, there is no steady state concentration of waste. The related problem for an unstable waste is examined, and it is found that a steady state condition can exist. The equation for this condition is derived. The problem of the time of occurrence of maximum concentrations at other than the discharge point is solved, and examples are shown of the use of the equations. The influence of boundaries on the distribution and concentration of wastes in tidal waters is examined initially for a one dimensional model and later expanded to three dimensions. Equations are derived showing the influence of boundaries, and a graphical technique that simplifies the use of the equations is shown. A method for the computation of mixing coefficients is illustrated, utilizing data that are readily available for most coastal waters in the United States.
