This test is based on Ebrahimi et al.50 experimental set up reported on
the transmission of the tidal oscillations in a lagoon. In this test a
trapezoidal barrier build of non cohesve sand seperates a closed lagoon from
the sea(fig. 14). Porosity and intrinsic permebelity of the barrier are 0.3 and

, respectively. The water level in the open sea was
fluctuated with an amplitude of 60 mm and a period of

 to apply the boundary
conditions. Figure 14 illustrates the dimensions of experimental setup and the
boundary conditions of the problem. Points A, B and C illustrated in this
figure are the places where the solutions are going to be presented and
compared with the experimental obsorvations. Point A and point B displays water
level fluctuations in the lagoon and in the open sea, respectively. On the
other hand, point C is used to illustrate the velocity fluctuations in the open
sea. More detailed descriptions of the measurements and data my be found in
Ebrahimi et. al. 50 and in Yuan et al. 26.  Konga et al. 25 and Li et al.23 have been
studied this experiment using finite volume/finite difference and control
volume methods, respectively. Here this experiment is solved with the use of the
new procedure of free surface tracking presented in this paper. To do so, the grid
size is taken as

 in tiangular shape. The
surface water level fluctuations evaluated in this paper
are compared with the experimental obsorvation in Figures 15 and 16 for point B and A, respectively, where an excellent
aggrement exists between two results. Moreover, the flow velocity predicted by
the present model for point C is compared with the experimental obsorvation in
Fig.17, where again an excellent matches achieved. It is worth mentioning that Reynolds number in this problem is less than 10, and Darcy assumption is acceptable to a
large extent12
