A01 shoaling and refraction
The purpose of this test is to verify the correct implementation of shoaling and refraction.
A domain with flat Inclined bottom is considered. The depth decreases from 10 m at y=0 to depth -1 m at y=4000 m.
At the Southern boundary (y=0) an incident wave field is assumed which propagates in a direction 30° from S. In order to come close to the analytical solution this incident wave field has a narrow frequency spectrum with a narrow directional distribution. The peak period is 10 s.
The analytical results are computed as follows; the wave direction (measured from the normal to the coast) results from Snel's law:
and the wave height from:
In plotfile A01.plt computed values for Hs and average direction are compared with the analytical results.
9 cases are considered:
In case A01h a table A01h.tbl is written which shows values of a number of variables along a straight line parallel to the coast; all variables should be constant along this line.
