Exploring the partial use of the Mo.S.E. system as effective adaptation to rising flood frequency of Venice

<p>The Venice lagoon (Italy) is particularly vulnerable to the impact of subsidence and sea level rise driven by climate change. Some structural measures have been adopted over time to protect Venice from flooding, among which a system of flap gates (Experimental Electromechanical Module, Mo.S...
