Modelling the Dispersion of Ship Emissions in Different Scenarios and Sensitivity Analysis

A modelling study, supported by a sensitivity analysis, is proposed for assessing the distinctive features of the dispersion of ship emissions in the Venice Lagoon. The main aspects on which the analysis focuses are the appropriate parameterization of the turbulence variables in the lagoon, the proper treatment of the lagoon-sea surface temperature and the evaluation of different parameterizations for the plume rise to describe the pollutant emissions from moving ships. The results of the study are discussed in the context of the environmental impact assessment of present and future scenarios.
