Abstract
Full solution of Boussinesq-type equations (two-dimensional in a horizontal
plane) with resort to a finite element method has mainly the following
advantages: i) it can be employed in any geometry, under complicated boundary
conditions, ii) different local resolution of the computational grid can be treated,
according to the bathymetric irregularities, without any additional computational
effort.
Nevertheless, in general, the solution of many real world problems using the
finite element method takes a long time from the computational point of view;
this prevents its use to obtain numerical solutions to the above mentioned
mathematical models. In practice, this inconvenience has lead frequently to the
use of mathematical models with lesser ability (p.e. the elliptic Berkho
