Dissolved oxygen measured vs modelled

Dissolved oxygen minimum values forecast

The possibility of operating the MOSE

System to increase water renewal in critical

areas is object of investigations.

Present results obtained through the trophic

model suggest that significant increase in

water renewal and hence in oxygenation

of water column may be obtained

especially in the areas close to the sub-

basins borders.

Not only flood defensethe MOSE barriers used to implement environmental measures

Climate Change adaptation

General Plan of complementary adaptive measures to climate change

for Venice

Adaptive management shall try

to maintain current functions of

the Venice system, including

those related to living and

working opportunities.

A shared vision must be

therefore defined. To realize the

new vision, innovative and

shared project modalities are

needed, in particular to reduce

decision timing, conflicts and

oppositions.

In this perspective, climate

change challenges represent an

opportunity for the Venice

system.

• Venice protected from the negative effects of climate change; • Improvement in the quality of the environment (water, sediments, etc.);• Increase in the biodiversity of the ecosystem;• Development of a system of multi-disciplinary knowledge and expertise;• Venice has become a reference for other countries facing sea level rise

Results achievedA general improvement in the lagoon ecosystem

Management and Control

• Engineering• Project and management• Monitoring• Control room

restored historic buildings

Start up of management procedures

Innovation and the Venice lagoonSafeguarding Venice. A wordwide reference

Special expertise in:

• Climate change and sea level rise adaptation measures;

• Coastal zones management and improvement of territory resilience;

• Balance in between natural and anthropic environment.

Multidisciplinary action:

Maritime, hydraulic and environmental engineering, construction management,

legal and administrative management, environmental sciences.

In such a context innovation plays a central role to provide new solutions to old

problems and to rethink existing instruments to face new challenges.
