In recent years, increasing attention has been paid to development within the port sector. One of the aspects of the sustainable development when it comes to coastal region is also intrusion in marine and coastal areas which often involve sediment dredging and disposal operations both ambient forcing and human activities. The increasing attention paid to this wide topic is also exacerbated by the exploitation of the coastal zone for National economic, touristic and social reasons. Indeed, estuarine, coastal, and harbor areas often undergo operations that temporarily increase sediment transport, e.g., for beach nourishment, for maintaining safe navigation depth in approach channels, and to remove contaminated sediment primarily to support their use. For example, to counteract erosion processes that degrade beach quality often, beach maintenance is required. To nourish beaches sand has to be dredged and moved. Moreover, harbor areas and navigation channels require maintenance dredging to allow the regular circulation of the vessels. The quantity of sediments to be dredged can vary in relation to the various purposes, e.g., to maintain or improve the navigation depth of ports and harbors, for creating or improving facilities, for beach nourishment and open-water disposal or morphological reconstruction in transitional areas. Common modeling approaches involves hydrodynamic and transport models suitable to quantify and to compare the transport processes of the different sediment. On the other hand, technical and scientific literature highlights the lack of an whole and comprehensive methodology driving the selection of appropriate modeling tools and of accuracy levels needed for a reliable assessment of the induced sediments handling operations. It has to be stressed that past studies found that results rarely focus on long-term effects of sediments dispersion, within either seasonal or annual they are focused on short-term scenarios usually related to either one or few tidal cycles or extreme events. This paper proposes a mathematical modeling approach intended to estimate the maintenance dredging in a port.
