“…This causes behaviors in harbor siltation to be very different depending on the port location. For example, in most fluvial and sea ports sediments are mostly located near the entrance of the basin, where the coarsest sediment fraction deposits as soon as the current decreases, while usually only the finest sediments can reach the furthest part of the basin, resulting in a non-uniformly distributed sedimentation [7,[21][22][23]. Conversely, when the sediments entering the port are only fine-grained, as occurs in semi-enclosed basins like lakes or coastal lagoons, they can remain in suspension for a longer period thanks to a much lighter fall velocity, and they spread all over the harbor before they deposit as the speed of the current decreases, for instance, during slack tides, resulting in a more uniform spatial distribution.…”

Port silting is a common and natural process which often causes serious inconveniences for safe navigation and requires expensive dredging operations to keep the port operative. Sediment deposition is closely related to the exchange water between the basin and the surrounding environment; one way to limit deposits is by reducing the flow entering the port. However, this may be in contrast with the need for adequate sediment quality, which in turn is closely related to an appropriate water current. This seems to be particularly important in lagoon environments, where sediments are often polluted, making its disposal more complicated and costly. The present paper investigates the situation of the port of Marano Lagunare (Italy) by means of a bidimensional morphological-hydrodynamic and spectral coupled model. To reduce the sediment input into the port, the closure of a secondary port entrance is usually suggested. However, this work demonstrates that a complete dredging of the secondary port inlet allows for an increase in water circulation or efficiency renewal, which ensures a better oxygenation at the bottom of the canals.
