Refraction parallel contour lines
For a given water depth the calculation rules calculate the wave height and the angle of wave approach (angle of the wave crest to the coastline) of regular long-crested waves that approach the coast from deeper water. Starting points are: - no current;
- method according to the linear wave theory;
- hard/rigid impermeable bottom with gentle slopes and parallel depth
contours;
- no reflection/refraction from the limits;
- no discontinuities in wave crests;
- the wave period is the same throughout;
- no dissipation of wave energy occurs.
