Abstract The effects of port spacing and jet momentum flux on the characteristics of submerged wastefields produced by multi-port ocean outfalls in linearly stratified currents were investigated experimentally. Within the parameter range studied the primary effect of these variables is on the rise height and thickness of the wastefield, and dilution is closely approximated by line plume results. Point plume results did not reliably predict properties in flowing currents due to rapid plume merging. Increased momentum flux causes a reduction in rise height at low current speeds while leaving the total entrainment path, and hence dilution, fairly constant, but exerts little influence at higher current speeds. Results are presented in graphical and tabular form from which rise heights and thicknesses can be estimated for outfalls which do not approximate line plumes, and an example of the procedure is given.
