“…The propagation from deep waters to the evaluation point has been done using the LIMWAVE numerical model (González-Marco et al, 2004). The LIMWAVE is a phase-averaged code based on the conservation of the wave action equation (for the wave height), the eikonal equation (for the phase information) and the irrotationality of the wave number vector equation (for the wave angle) as described in Ebersole (1985) and Liu (1990). This model incorporates a depth-limited breaking dissipation according to Dally et al (1985) for regular waves and according to Battjes and Janssen (1978) for irregular waves.…”

“…By the use of irrotationality of the gradient of the wave phase function following equations can be derived; (6) (7) in which , : unit vectors in the x and y directions, respectively; q(x,y): angle of incidence defined as the angle made between the bottom contour normal and the wave direction. q(x,y) can be found from the following expression; (8) The following energy equation is used to determine wave amplitude; (9) Eqn (6) together with Eqn (2) and Eqn (7) result in the set of three equations that will be solved in terms of three wave parameters, wave height H, local wave angle q and Ω-sΩ (EBERSOLE, 1985). (10) (11) Eqns (8), (10) and (11) describe the refraction and diffraction phenomena.…”

“…The other assumption is that reflected waves are neglected. When the bottom contours are not straight and parallel as in the case of complex bathymetries, the requirement that one grid coordinate should follow the dominant wave direction causes problems (EBERSOLE, 1985).…”

“…Ebersole (1985) desarrolló un modelo de propagación, RCPWAVE, que resuelve las ecuaciones (32) (33) y (17) sobre una malla en diferencias finitas. A pesar de que este modelo no tiene la limitación del ángulo, presente en los modelos parabólicos, sí tiene algunos inconvenientes.…”
