Module selection
This version of MIKE 21 BW includes two modules:
2DH Boussinesq wave module
1DH Boussinesq wave module
The 2DH module (two horizontal space coordinates) solves the enhanced
Boussinesq equations by an implicit finite difference techniques with variable
defined on a space-staggered rectangular grid. This module is typically
selected for calculation of short and long period waves in ports, harbours and
coastal areas, see Examples in Section 4.2.

Example of a MIKE 21 BW 2DH application
The 1DH module
(one horizontal space coordinate) solves the enhanced
Boussinesq equations by a standard Galerkin finite element method with
mixed interpolation on an unstructured grid. This module is typically selected
for calculation of wave transformation from offshore to the beach for studying
surf zone and swash zone dynamics, see
Figure 5.3
Example of a MIKE 21 1DH application
