Improvement in the Sediment Management of a Lagoon Harbor: The Case of Marano Lagunare, Italy

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