High-frequency gravity waves, such as those associated with an undular
bore, that do not leak a significant amount of energy vertically and instead propagate horizontally for long distances are said to be "trapped" (Scorer 1949).
The secondary layer may generally be subdivided into two main sublayers: the about 400 [micro]m thick outer sublayer with undular
laminae of the ribs (Fig.
Numerical results of the Rosenau-KdV equation are obtained for four test problems: the motion of single solitary wave, interaction of two and three solitary waves, evolution of solitons with undular
bore initial condition.

On the other hand, for the same initial conditions as the ones discussed above but with dispersion and no diffusion, the initial steepening of the leading part of the initial profile caused by the nonlinear advective term is eventually somewhat balanced by dispersion and a dispersive shock wave or conservative undular
bore may form [17, 20, 21].

The RLW equation was introduced in  where it was used to describe the behaviour of the undular
where [mu] is a positive constant, is a nonlinear evolution equation, which was originally introduced by Peregrine  in describing the behavior of an undular
bore and studied later by Benjamin et al.
Jump became undular
at the discharge of 500000 and 1000000 cusec as upstream Froude number became 1.63 and 1.85, respectively.
Sea como sea, parece que en espanol -salvo los grupos 'un' y 'mil', (undular

For, aside from surmising that wavelike properties must be associated with microcosmic entities, de Broglie also specified the measurable aspect (wavelength) of this undular
