<ref name="Karsten"/>The outer limit of the breaker-zone is called the [[Breaker line]]. However, the instantaneous width of the surf-zone varies with the instantaneous wave conditions. In this context we define the surf-zone as the zone valid for the yearly wave climate defined by the significant wave height H<sub>S,12h/y</sub>, which is the wave exceeded 12 hours per year.

The width of the breaker/surf-zone can thus be defined as the width of the zone within which H<sub>S,12h/y</sub> breaks. The breaker/surf-zone is somewhat narrower than the littoral zone. It is evaluated that 80 to 90% of the yearly littoral transport takes place within the breaker or surf-zone.

Definition of Breaker zone:
The zone within which waves approaching the coastline commence breaking (typically in water depths of between 5 and 10 metres).[1].
This is the common definition for Breaker zone, other definitions can be discussed in the article


Notes

  • The breaker zone is a subset of the surf zone.
