A COMPARISON OF HIGHER ORDER BOUSSINESQ AND LOCAL POLYNOMIAL APPROXIMATION MODELS

Mauricio F. Gobbi, Andrew B. Kennedy, James T. Kirby

Abstract


Two recent approaches for computing wave evolution over varying topography are presented: the high order Boussinesq model of Gobbi and Kirby (1998) and the local polynomial approximation (LPA) method of Kennedy and Fenton (1997). Both analytical results and numerical solutions of Gobbi and Kirby (1998) model and two variants of the LPA method are presented and compared with exact solutions and laboratory measurements of waves propagating over submerged features

Keywords
