Theoretical and experimental studies were performed on the dispersion and settling of barge disposed wastes in the ocean. A computer program based on the mathematical model has also been written. Comparison of predictions with experiments, both in this study and from previous investigations were found to be good. Example solutions based on the model for prototype situations are also presented. The waste is assumed to consist of two phases: (1) A solid phase characterized by constituents with various densities and fall velocities, and (2) a liquid phase. The methods of disposal considered include (1) discharge from a bottom opening hopper barge, (2) pumped discharge through a nozzle under a moving barge, and (3) discharge into the barge wake. The effects of ambient horizontal currents, density stratification, variation of diffusion coefficients are incorporated in the model. Three phases of dispersion are envisioned: (1) A convective phase; (2) a collapse phase; and (3) a long term diffusion phase. Transition between phases is accomplished automatically in the numerical model. (Modified author abstract) Portions of this document are not fully legible.
