Study of water quality in a port through numerical modeling

The deterioration in water and sediment quality, along with the decline of marine ecosystems, can be attributed to a combination of natural and human-induced factors. A significant concern arises from the lack of water mixing, particularly in ports and harbors characterized by their enclosed or semi-enclosed nature. This situation can lead to stagnant water conditions, facilitating the accumulation and concentration of pollutants. To address these issues, it is important to adopt effective environmental management practices within and around ports and harbors. In this study, the focus is on a 3D numerical model that is utilized to identify the hydrodynamic circulation and assess water renewal within a port situated on the southern Adriatic coast of the Apulian region in southern Italy. Specifically, the study delves into the simulation of real scenarios involving potential pollution within the port, resulting from heavy rainfall and the subsequent overflow of the sewer system.
