Sediment in Venice

Inspired by my upcoming trip to Italy, my discussion this week looks at sediment in a lagoon in Venice. Venice is a city in Northern Italy that is made of many different islands that are connected by canals and bridges. The Venetian Lagoon is the overall term for the area encompassing Venice. Humans have had some significant impacts on the lagoon including subsidence, pollution, fishing, and erosion. The Lagoon has been dredged in many places to deepen the channels which helps contribute to the erosion.

I don’t think that we have any place in the US that is made of many islands such as this, and so we haven’t had to deal with the sediment/flooding issues that Venice does. Do you think that if we did we would have just filled in all the channels and made more space for development?
