حواجز فيضان البندقية تهدد بقطع المدينة عن البحر

By Phil Bainbridge

May 19, 2023 - بعد عدة قرون من الفيضانات، تستخدم البندقية MOSE - وهو عبارة عن نظام من الجدران البحرية تبلغ كلفته 5 مليارات دولار - مراراً أكثر مما كان متوقعاً حيث تواجه واقع تغير المناخ وارتفاع مستويات سطح البحر.

MOSE comprises 78 flood barriers that guard the three entrances to the lagoon in which the Most Serene Republic was established over 1,500 years ago. Designed to protect the city against tides of up to 3 metres, they were nevertheless expected to be used only five times a year for tides of over one metre.

However, a combination of tectonic settling over thousands of years, extraction of groundwater for industrial needs in the 20th century and rising sea levels due to climate change has meant the barriers have instead been used almost 50 times in just two years. The increasing frequency of their use is now threatening to affect the natural flow of water between the lagoon and the Adriatic Sea.
