| Abstract |
|
The Venice Lagoon is a complex system and increasing pollution problems and silting-up of interior channels are threatening its unique appearance and environment. For instance, particulate matter loadings, originating also from human wastes, have increased the channels’ natural tendency to accumulate sediments. This brings as a consequence a modification in the tidal propagation within the lagoon channels and an increased possibility of releasing toxic substances during resuspension periods. Moreover, severe problems have to be addressed when, after channels dredging, sediments need to be properly disposed. In order to preserve the delicate lagoon ecosystem, therefore, a modeling apporach combining the hydrodynamic behaviour of the Venice Lagoon and the sediment distribution to better understand the relation between them is highly desiderable. As a preliminary step towards this direction, we present here a coupled hydrodynamic-wave model, reproducing the circulation of the Venice Lagoon and the effects that winds may have on the wave-currents interactions. Particularly, the study is focused on the determination of the bottom stress values, the main forcing for erosion and deposition processes. Sensitivity tests adopting only currents and wind at different speeds and directions have been performed and results are presented and discussed. Added by: Dott. Alessandro Meggiato |
