Since our last meeting, we have been successfully receiving e-mails with the forecasts. We have spent the last couple of weeks working with the sensors and the floods. We have used pavement height data provided by Insula SpA to start observing how our test island (Santa Ternita) acts during floods. We predicted which streets would flood and then went there during the high tide to confirm if our logic was correct. We also went to Piazza San Marco and other flooded streets, compared the tide level to the pavement height data we have in order to confirm if the logic we are using was correct.
Around that time, we met with Oreste Vernier at Eraclit, in order to get the sensor. We started by installing the sensor at Santa Ternita. We also have installed the sensor at Fondamenta San Severo, Fondamenta Nani in Dorsoduro, and Fondamenta San Felice in Cannaregio. We strategically chose those locations in order to check water level behavior at different places in Venice and therefore improve our logic when determining when each street would flood based on Punta Salute. While we were doing that, we have also been working on our report and we developed a web visualization for the water level at different segments of different canals at each hour. We used the forecasts to run the hydrodynamics model and extract the water level at each of the 505 links in Venice. Then we used those water levels at each hour to create the visualization. Our next step will be to extend this visualization in order to compare the water levels with the pavement height to allow street flooding visualization.
