Fluid sheets wave theory-gn wave model

WebMay 1, 2008 · The different degrees of complexity in the GN theories are distinguished by ‘levels’. For shallow water waves, Level I GN theory (here after, GN-1) was used to simulate some nonlinear wave flows [9,29]. Nadiga et al. [23] studied the overturns of isopycnal surfaces by use of the GN-1 model.
