Abstract

SUMMARYWe extend the framework of the finite volume method to dispersive unidirectional water wave propagation in one space dimension. In particular, we consider a KdV–BBM‐type equation. Explicit and implicit–explicit Runge–Kutta‐type methods are used for time discretizations. The fully discrete schemes are validated by direct comparisons to analytic solutions. Invariants' conservation properties are also studied. Main applications include important nonlinear phenomena such as dispersive shock wave formation, solitary waves, and their various interactions.

Summary

Introduction

Water wave modeling is a complicated process and usually leads to models which are hard to analyze mathematically as well as to solve numerically. A wide range of numerical methods have been employed to compute approximate solutions to dispersive wave equations of KdV-BBM type : finite difference schemes [10, 50], finite element methods [9, 33, 2] and spectral methods [38, 39, 15, 35]. In order to apply the finite volume method to the KdV-BBM equation (1.1), we rewrite it in a conservative form, including a nontrivial evolution operator, an advective and a dispersive flux functions. Strong Stability Preserving Runge-Kutta (SSP-RK) methods, which preserve the TVD property of the finite volume scheme, [44, 24] are used for the explicit discretization.
