Hydrodynamic Modelling

Through the application of sophisticated 3d hydrodynamic models, ONS is able to reproduce the natural regional oceanic variability both at the continental shelf scale and estuarine scales.  The output includes 3d current structures, density profiles, internal waves, tidal conditions.

For regional shelf scale applications, the models are driven by available global databases to represent the longer term boundary conditions, tidal conditions, and atmospheric influences such as air-sea heat fluxes, wind and pressure and other forcing conditions.
