3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Split flow
The radiation stress changes caused by the uneven breaking of the waves and the wave water pressure gradient act together to produce a jet stream from the coastline to the breaking wave zone.
Note. Rewrite GB/T 15920-2010, definition 2.3.73.
3.2
Waves
The sea surface fluctuation phenomenon caused by wind mainly includes wind waves and swells.
[GB/T 15920-2010, definition 2.4.1]
3.3
Effective wave height
Arrange the wave height sequences continuously measured in a certain period from large to small, and take the average of the first 1/3 wave heights after sorting.
[GB/T 15920-2010, definition 2.4.36]
3.4
Rift disaster
Disaster caused by casualties caused by cracking.
