General Curvilinear Coastal Ocean Model


2016-04-28_21-56-30

The GCCOM model is capable of  reproducing non-hydrostatic features such as the interaction of currents with steep bathymetric features at high resolutions.

Areas of Applications: Stratified and density driven flows, Hydrodynamic simulations,  Thermal stratification in lakes, seas and reservoirs, Non-hydro-static flows:Internal Waves, Internal Tides, Internal Bores.
