EA:  SURGING_BREAKER_FRACTION

Status: STD 2005/06/07
Code: 1393
Concept definition: A number between 0 and 1 inclusive representing the linearly-scaled fraction of breaking <WATER_WAVE>s within a delineated <WATERBODY_SURFACE_REGION> that are surging. Surging means that the <WATER_WAVE> crest tends to advance faster than the base of the <WATER_WAVE> to suggest the formation of a plunging breaker, however, the <WATER_WAVE> base then advances faster than the crest, the plunging is arrested, and the breaker surges up the <BEACH> as a wall of <WATER> which may, or may not, be white water. Zero means no breaking <WATER_WAVE>s are surging and one means all are surging.
