The Lagoon of Venice is the largest in all of Italy, stretching roughly 15 kilometers in length and 8-14 kilometers wide. The lagoon consists of a network of channels, islands, and marshes. Venice itself lies at the very center of the lagoon. The lagoon's geology consists of a layer of bedrock at the bottom, piled with several layers of clay and sand, followed by a less solid layer of clay, and finally layered on top with sand and gravel.
This is an important point to consider for our project. Many potential transportation systems we are researching include digging tunnels underneath Venice and therefore the lagoon. The problem with this is that the layers of clay and sand are not solid by any means. In fact, the layers eroding from the lagoon are causing the sea level to rise. Installing supports for any underground tunnels would no doubt increase the expected cost. This is one of many important factors to consider for our report.
