The width of the instantaneous littoral zone varies dependent of the wave conditions. In the general context, we will define the littoral zone as the zone corresponding to the yearly wave climate. The width of the littoral zone can thus be defined as the width of the transport zone for the significant wave height, which is exceeded 12 hours per year, H_S,12h/y.
