The oceanographic forecast capability in coastal seas is often limited by the capacity of the numerical models in correctly reproducing the complex morphology of the coastline and the exchange processes between the shelf and the open seas. In the marginal Adriatic Sea this task is of uppermost importance due to the presence of several coastal water bodies and rivers. We present here a new oceanographic system, based on the unstructured grid model SHYFEM and representingthe whole Adriatic Sea together with the lagoons of Marano-Grado, Venice and Po Delta. The innovative aspect of the oceanographic system for the Adriatic Sea presented in this study is that it accurately addresses land-sea, air-sea, and coastal-offshore interactions. These processes are taken into account in the forecasting system by adopting adjourned discharge for most of the rivers, by forcing the hydrodynamic model with high-resolution meteorological fields, and by resolving the lagoon-sea and the river-sea continuum using a very high-resolution, up to 10 m, numerical mesh. The presented results highlighted the capacity of the developed system in simulating the general circulation in the Adriatic Sea, as well as several relevant coastal dynamics, such as tidal dynamics, saltwater intrusion, storm surge and riverine waters dispersion.

Abstract
The oceanographic forecast capability in coastal seas is often limited by the capacity of the numerical models in correctly reproducing the complex morphology of the coastline and the exchange processes between the shelf and the open seas. In the marginal Adriatic Sea this task is of uppermost importance due to the presence of several coastal water bodies and rivers. We present here a new oceanographic system, based on the unstructured grid model SHYFEM and representingthe whole Adriatic Sea together with the lagoons of Marano-Grado, Venice and Po Delta. The innovative aspect of the oceanographic system for the Adriatic Sea presented in this study is that it accurately addresses land-sea, air-sea, and coastal-offshore interactions. These processes are taken into account in the forecasting system by adopting adjourned discharge for most of the rivers, by forcing the hydrodynamic model with high-resolution meteorological fields, and by resolving the lagoon-sea and the river-sea continuum using a very high-resolution, up to 10 m, numerical mesh. The presented results highlighted the capacity of the developed system in simulating the general circulation in the Adriatic Sea, as well as several relevant coastal dynamics, such as tidal dynamics, saltwater intrusion, storm surge and riverine waters dispersion.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
