Abstract: Experiments were performed to measure the ultimate surface dilution of plumes typical of those from multiport ocean outfall diffusers. The discharge was from both sides of the diffuser into stationary, unstratified water. Considerable mixing occurs in the spreading layer of an isolated point plume, resulting in ultimate dilutions about three times higher than at the plume centerline. The additional mixing for fully merged plumes results in dilutions about 1.2 times higher than at the centerline. Results are presented from which dilution can be predicted for multiport diffusers with arbitrary port spacings, and in the point-and line-plume limits.
