environmental impact assessment and risk analysis

Course objectives

The course aims to allow to carry out Environmental Impact Studies or to verify their completeness the reliability through the most current methodologies for the study of the dispersion processes of contaminants in the environmental and environmental sectors their interaction with the final receptors. The course includes the analysis of the main chemical-physical processes that govern the phenomena of transport and dispersion of contaminants into the atmosphere, surface water, groundwater and unsaturated area and the fundamental indications for the use of models suitable for the study of the processes described. Ability to create an SIA in the form required by the entities, mastery of transport and dispersion processes, risk analysis applied to soil and subsoil remediation. The course is strongly aimed at mastering the technical methodologies for assessing the impacts related to works and infrastructures to be carried out on the territory, the student deals with the various environmental elements deepening issues concerning the physics of the same (knowledge and understanding) that influence the fundamentals processes of the fate of pollutants in the various sectors. Applied cases are also studied in order to transfer training knowledge to their application (Applying knowledge and understanding). The student also acquires the ability to manage the different skills involved in drafting an SIA by using the knowledge acquired to define scenarios and make hypotheses (making judgments). There is no lack of reference to other situations in which the use of numerical models allows to solve environmental problems (e.g. remediation) (learning skills)
