Fluid Mechanics Aspects of Ocean Outfalls

Document Type: Proceeding Paper

Part of: Hydraulic Engineering


Prediction of the environmental effects of ocean outfalls requires understanding of some complex fluid mechanical phenomena. These include the dynamics of merging plumes in flowing, density-stratified environments, the collapse of turbulence under the influence of ambient density stratification, and the behavior of submerged and surfacing density currents. Recent advances in laboratory and field instrumentation has yielded advances in our understanding of these phenomena and improved models of outfall mixing. The purpose of this paper is to review outfall fluid mechanics and to give examples of the applications of new techniques.
