Minimize Venice, Italy

The images below present a view of the city of Venice. Venice is a city in northeastern Italy sited on a group of 118 small islands separated by canals and linked by bridges. It is located in the marshy Venetian Lagoon which stretches along the shoreline, between the mouths of the Po and the Piave Rivers. Venice is renowned for the beauty of its setting, its architecture and its artworks. The city in its entirety is listed as a World Heritage Site, along with its lagoon. Venice is the capital of the Veneto region. In these images we want to show a comparison, using the same satellite family but with two different sensors and two different images, acquired on different dates, of the lagoon and city area, and also to show the area where the MOSE Project is still under construction.

MOSE Project (Experimental Electromechanical Module)

These comparative images from Landsat 5 TM and Landsat 8 OLI, acquired in the months of August 1985 and September 2013, show the work in progress for the protection of the lagoon of Venice from high tides. The project originated in the 1980s and construction of the MOSE project began along the coasts of the lagoon in 2003. This project (Experimental Electromechanical Module) is designed to protect the city of Venice and the Lagoon of Venice from flooding. The project is an integrated system consisting of rows of mobile gates installed at the inlets of Lido, Chioggia and Malamocco that are able to temporarily isolate the Venice lagoon from the Adriatic Sea during high tides. Together with other measures such as the strengthening of the coasts, the collection of docks, and the paving and improvement of the lagoon (visible in the image acquired in 2013), MOSE is designed to protect Venice and its lagoon from tides of up to 3 metres.

The objective of MOSE is to protect the lagoon, its towns and villages, its people and its historical, artistic and environmental heritage from floods and extreme events. Although the tide in the lagoon basin is lower than in other areas of the world (where it can reach up to 20 m), the phenomenon may become significant when associated with atmospheric and meteorological factors such as low pressure and the Bora, a northeast wind coming from Trieste, or the sirocco, a hot wind from the southeast. These conditions push the waves into the Gulf of Venice. The high water is also worsened by the rain and the water flowing into the lagoon from the drainage basin in 36 points of influx associated with small rivers and canals.

Landsat 8 OLI

This image, acquired in the month of September 2013 by the Landsat 8 satellite, shows the city of Venice and relative lagoon area. The construction of the MOSE Project is also visible in this image, along the lagoon coast (see the images above for reference). This image aims to promote the opportunity to download Landsat data through the ESA portals, where images captured every day are made available in near real time to the users and the scientific community.
