DISCUSSION OF NOTE ON A NONLINEARITY PARAMETER OF SURFACE-WAVES BY BEJI,S

A recently proposed rescaling of the governing equations for inviscid, irrotational, free surface hydrodynamics is reconsidered. A redefinit ion of the proposed scaling parameters leads to a nondimensionalized p roblem which contains both the usual intermediate depth scaling and th e shallow water scaling as asymptotic limits, thus eliminating the nee d for a separate development of scaling arguments for the two regimes as given in most standard references.
