Variable depth KdV equations and generalizations to more nonlinear regimes

Samer Israwi (2010)

We study here the water waves problem for uneven bottoms in a highly nonlinear regime where the small amplitude assumption of the Korteweg-de Vries (KdV) equation is enforced. It is known that, for such regimes, a generalization of the KdV equation (somehow linked to the Camassa-Holm equation) can be derived and justified [Constantin and Lannes,   (2009) 165–186] when the bottom is flat. We generalize here this result with a new class of equations taking into account variable bottom...
