DI NATALE, M., MAIETTA, M., DI MAURO, A and DERI, M., 2011. Hydrodynamic Dispersion of Pollutant Discharge by Means of Submarine Pipelines. In: Micallef, A.

Anthropic activities have an important influence on the ecological state of seawater, so innovative systems able to guarantee water quality and minimize human impact are required. In this paper the pollution of Litorale Domitio coastal waters is investigated. The analyzed coastal areas represent the final discharge of treated wastewater and drainage water. Therefore an evaluation of a technical solution able to make the quality of such waters compatible with the tourism is needed. For this reason, the integration of the depurative scheme with a system of submarine pipelines is proposed. An application of the proposed method is shown with reference to the case of Regi Lagni in Campania. Using numerical models by DHI dedicated software, it is verified that the suggested method contributes to a meaningful reduction of near-shore pollution.
