TIDES in venice
“Acqua Alta” (High Tide)
140 cm exceptional high tide
110 ÷ 139 cm very high tide
90 ÷ 109 cm high tide
-50 ÷ 89 cm NORMAL TIDE
-90 ÷ -51 cm tide under the normal level
< -90 cm exceptional low tide
“Acqua bassa” (Shallow water)
Tidal Forecasting and Early Warning Centre (Centro Maree) Tasks of Centro Maree • Meteo-mareographic monitoring in the lagoon of Venice and in the sea facing it • Calculation of the astronomical tide in Venice • Forecasting of tide level • Forecasting on the state of the sea (wave height/direction) • Information and early warning • High tide walkways system management
Tidal Forecasting and Early Warning Centre (Centro Maree)
Meteo-mareographic Monitoring stations:
11 in the lagoon
Monitoring Network 3 at the inlets
2 offshore
2 repeaters
Measured parameters:
- sea level
- waves height
- atmospheric pressure
- wind speed and direction
- humidity
- air and water temperature
- solar radiation

Mobile barriers at the lagoon inlets (MOSE) The mobile barriers at the lagoon inlets are being constructed by Ministry of Infrastructure and Transport. Work began in 2003 and it’s expected to be completed by the end of 2021.

How EU projects are helping our job I-STORMS and STREAM are two integrated projects. These projects are inspired by a basin scale aproach. To increase the accuracy and reliability of sea storm forecasts is important to use the right scale, that is the adriatic-ionian area. This is only possible through the transnational cooperation.
The I-STORMS project
I-STORMS is a project co financed Common
Understanding
by the INTERREG Adrion programme
and led by the City of Venice
Increased
I-STORMS aimed at enhancing knowledge
innovative policies and develop joint

-increasing accuracy and reliability

Strategic development of flood management
STREAM aims to increase the
management capacity to promptly react
to flood disasters in the Adriatic coastal
area by developing:
●
Efficient risk monitoring tools and early
warning procedures
●
flood risk management plans
●
flood forecasting system
Data sharing, flood cadastre, flood risk
maps, exchange of practices and capacity

The project will also contribute to raise
awareness about the flood risks in the
areas involved and to people will learn
how to behave in case of flood hazards.Tidal Forecasting and Early Warning Centre Thank you!
