非平底KdV-type的新非线性方程

New nonlinear equation of KdV-type for a non-flat bottom

Anna Karczewska, Piotr Rozmej, Łukasz Rutkowski

摘要:

本文导出了一个新的直接考虑海底地形的浅水波非线性方程。该方程在弱非线性、色散和长波长范围内是有效的。根据导出的方程,给出了在数值模拟中得到的各种底部形状的孤子运动的一些例子。

英文摘要:

In the paper a new nonlinear equation describing shallow water waves with the topography of the bottom directly taken into account is derived. This equation is valid in the weakly nonlinear, dispersive and long wavelength limit. Some examples of soliton motion for various bottom shapes obtained in numerical simulations according to the derived equation are presented.
