The Moses is an experimental anti-flood system used in Venice. It consists of 78 barriers that can be inflated like a ‘dike on-demand’. The barrier is movable and capable of protecting the city from tides as high as 3m. It was put in place after Venice experienced its worst floods in 50 years. Recently, the barriers weren’t activated in time, as winds, stronger than predicted, propelled tidal waters into the city leading to flooding.
