    Description: This dataset includes the results of the application of the SHYFEM numerical model to the Po River-Delta-Sea (RDS) system (Italy). The hydrodynamics and the interaction between riverine and marine waters in the system were studied through the application of the unstructured finite elements 3D numerical model to a domain comprising the Po river branches, 7 coastal lagoons and the shelf sea. The vertical structure of the model is z-levels, with 1 m thickness up to 10 m depth, 2 m thickness up to 26 and finally 4 m thickness to 34 m depth. The model was forced with real data of water levels, meteorological parameters and freshwater inputs. The simulations included the baroclinic gradients in the hydrodynamics calculations induced by mixing of riverine and sea waters, and by heat fluxes with the atmosphere. Two simulations were run, one for the model calibration (March - September 2009) and a two year long simulation (2010-2011) for the model validation and analysis. The SHYFEM parameter files of the two simulations are included in the data archive. The dataset includes the time-averaged hydrodynamic and T/S fields of the two simulations and of a relevant river flood in May 2009. For the 2010-2011 simulation we also provide the Water Renewal Time distribution and its range of variability. The model values calculated on the triangular finite elements grid (scalar values on the nodes and velocities on the elements) were converted into a regular grid netcdf format with horizontal spacing of 100 m. The reference coordinate system is EPSG 3003.

    Description: The database include the ebb, flood and residual velocity fields obtained by the application of the SHYFEM model to the Venice Lagoon. The water circulation in the Venice Lagoon, induced by tide, wind, and water, heat and salt fluxes, was simulated by the unstructured model SHYFEM applied over a spatial domain that represents the entire Lagoon and its adjacent shore with 144361 triangular elements of variable form and size . The water column is discretized into 22 vertical levels with progressively increasing thickness varying from 1 m for the topmost 16 m to 7 m for the deepest layer of the outer shelf. The model was applied for the year 2014 in a 3-D baroclinic mode using observed forcing and boundary conditions (i.e. wind stress, heat and salt fluxes, precipitation, sea level and freshwater discharge). The residual currents are obtained averaging the modelled currents over the one-year simulation. By comparing model results with sea level data recorders at 26 gauge stations distributed in the lagoon, we estimated an overall root mean square error of 2.1 cm for the simulated water level. The components of the 3D velocities are provided for each node of the numerical domain.
