Turbulent Kinetic Energy
Coupling of wave and circulation models in coastal–ocean predicting systems: a case study for the German Bight
... The original version of GETM was modified to account for the depth-dependent radiation stress and Stokes drift. The terms were calculated from the integrated wave parameters according to Mellor (2008, 2011) and Kumar et ...
