An integrated and sustainable observing system for the implementation of a Coastal Digital Twin of the Ocean

The coastal zone provides opportunities for a variety of users which can affect the availability of space and the conservation of important habitats. Coastal zone also represents the area of both anthropic and natural inputs through rivers, which can be an important pressure due to the potential introduction of pollutants and the increasing flooding. Latium coast represents and important area for the presence of the Tiber river which affect a big portion of the region. Moreover, this area is an important site for big coastal infrastructures that potentially produce direct and indirect impacts on marine ecosystems, particularly Posidonia oceanica seagrass meadows, rocky and algal reefs. This work shows an integrated and advanced observing system, including autonomous platforms, cost-effective technologies and numerical modeling, applied to the study of the interaction between anthropic pressures and natural resources in order to realize a Digital Twin of the Ocean of this coastal area toward the implementation of nature based solutions.
