Abstract: Submarine outfalls are the most commonly used alternative for coastal cities sewage and industrial disposal. In this paper, the study of different submarine outfalls solutions is presented. In the process two models were used: an hydrodynamic baroclinic 3D regional nested model and a local substance transport lagrangian 3D model. The hydrodynamic model has four nested three-dimensional grids. The last level has a high resolution mesh (100 m spacing) and was calibrated using the vertical current profile obtained with two ADCPs located in the zone. The lagrangian model includes a jet model and a far field transport model. These models were applied to resolve the final disposal problem of two Uruguayan's coastal cities: Montevideo and Punta del Este. The final result of the whole process is a submarine outfall design that verifies the economic and environmental requirements.
