Title: Hydrodynamics of the Inner Canals of Venice


1
Hydrodynamics of the Inner Canals of Venice
  • Sponsored by
  • UNESCO-ROSTE
  • in collaboration with
  • Insula S.p.A.
  • Christine Biscotti Andrea Emery
  • Maxwell Pistilli Joseph Zsofka

2
Project DescriptionDescrizione del Progetto
  • Purpose To characterize the hydrodynamics of the
    inner canals of Venice

3
Applications of ResultsUtilizzo dei risultati
  • Validation of the sedimentation model
  • Contribute to the scheduling of maintenance of
    the canals

4
Reasons for MaintenanceMotivazioni per la
Manutenzione
  • Lack of a modern sewage system
  • Continuous build-up of sediment in canals
  • Results of these problems
  • Shallow water depth for boats
  • Wall damage
  • Poor hygiene of water

Conclusions Conclusioni
  • Unusual flow behavior demonstrates the need for a
    sedimentation model
  • Flushing ability has a bigger impact on sediment
    removal than flow velocity alone
  • Effective use of this information will lead to an
    efficient maintenance schedule
