“Acqua Alta” Alarm in Venice, exceptional event of last November monitored and forecasted

UNESCO World Heritage Site since 1987, Venice with its canals, squares and churches is a source of pride for Italy and the Italians. Located within the Venetian Lagoon, the city is a living work of art that is visited by 25 million tourists a year.

The extraordinary event of “Aqua Alta” (means= “High Water”) occurred recently in Venice (see article: www.nytimes.com/2019/11/13/world/europe/venice-flood.html) highlighted once again the problems generated by climate change and the need to have efficient and accurate hydro-meteorological monitoring networks in order to promptly alert the authorities and the population. The term Acqua Alta is a Venetian expression that indicates the phenomenon of particularly pronounced tidal peaks that occur in the Venetian lagoon during the autumn / winter season when the astronomical tide, the sirocco wind, the phenomenon of the sex in the Adriatic (or even all these elements) cause a greater influx of water into the lagoon.

The Centro Previsioni Maree plays an important role in terms of forecasting the tidal and forecticasting the “Acqua Alta” phenomenon using data from a hydro-meteorological monitoring network provided and maintained by Siap + Micros SpA inside the Venetian lagoon.

The need to perform an accurate meteo-marine monitoring is explained by Alvise Papa (Manager of the Center for Tide Forecasts) during an episode of Linea Verde Life broadcast on 26 October. At the following link the episode aired on Rai Uno (National Italian Television) where you can see Siap+Micros SpA’s technology:
