ABSTRACT A new type of extended Boussinesq model has been developed using a mathematical artifice that decomposes each vertical component of velocity on a series of functions on the water depth. This mathematical artifice enables to improve its linear dispersion behaviour by increasing its frequencial range of validity and also to improve its ability to reproduce vertical velocity profile and to deal with linear shoaling and steep slopes. The aim of this paper is to present the theoretical bases of this finite elements model and also to study its non-linear 2nd and 3rd order behaviour and its ability to deal with linear shoaling.
