The Extended KdV Equation: Augmented Lagrangian and Variational Solitary Waves with Applications to Dispersive Hydrodynamics
Saleh Baqer, Hamid Said
In this work, we extend the method of averaged Lagrangian to the study of the general second-order (non-conservative) extended Korteweg--de Vries equation, known as the eKdV equati…

A study of variational single solitary waves governed by the conservative-extended KdV equation with applications to shallow water dispersive shocks
Saleh Baqer, Hamid Said
The extended KdV equation is a nonlinear dispersive wave model that is asymptotically or variationally derived from the full dispersive Euler shallow water waves equations when gra…
