Bacan: Venice's new island - nature meets technology in the lagoon!
A fascinating change in nature takes place in the Venice lagoon: The former seasonal sandbar Bacan has developed into a constant island in recent years. This transformation is significantly influenced by the Moses Flood Protection System, which was activated in 2020. The engineer Giovanni Cecconi from the Università Ca 'Foscari in Venice explains that the Bacan barrier protects against the huge waves in winter and increases the water flow in the lagoon in summer. This promotes the deposition of sediments that supports the growth of the island. According to reports from OE24 and Ilfattoquotidiano, the island has now reached a length of 250 meters and a width of 10 meters, completely covered by domestic vegetation.
The changes in detail
So far, Bacan has only been visible during the summer months, since storms and floods often continue the sandbar in winter. But due to the Moses system, which stops high water levels over 110 centimeters, Bacan can now survive all year round. The small sandbar, which previously equalized a simple gravel bed, became a striking island. "What was a low sand heap at the time has now developed into a new island," continued Cecconi. The new conditions also favor the settlement of robust plant species that stabilize the soil and protect against erosion. Despite this impressive natural development, experts warn of the complex ecological risks. Professor Andrea d’Alpos from the University of Padua emphasizes that the emergence of Bacan was also influenced by previous ecological factors and that the stability of the island is considered in the face of changing environmental conditions. The long -term loss of sediments that were previously transported to the region by winter floods applies. These sediments are important for the ecosystem because they strengthen coastal protection and carbon binding. The protection of Bacan by the Moses system could therefore have negative effects on other parts of the lagoon. Nevertheless, Bacan remains a fascinating example of the adaptability of nature and the challenges that modern technology brings with it, as the analyzes of OE24 and Ilfattoquotidiano make clear.| Details | |
