• 110,000 Lire/mc" (nel 1989)• 150,000 Lire/mc (nel 1996)
From Professor Carrera’s report, ‘Le CARATTERISTICHE FISICHE dei Canali Interni di Venezia’
• Estimate current price to about 200,000 Lire/mc
• Conversion to Euros ≈€100/mc

Grazie Mille!
Team Hydro would like to thank…
…The Instituzione Centro Previsioni e Segnalazioni Maree for taking the time out of their busy schedules to give us a tour of their facility, to provide us with daily tide forecasts through personal e-mail and to provide us with the details that we needed to complete this project.
…Georg Umgiesser, Elisa Coraci, and Luca Zaggia, of ISMAR, for collaborating with us on the model.
…Paolo Peretti, of IPROS, for lending us all of his equipment, and taking the time to take us out on his boat.
...And lastly to our advisors Professor Fabio Carrera and Professor Frederick Bianchi for without their guidance we would not have been able to complete this project in such a successful manner.
