SEA LEVEL RISE SECTIONS CRISSY FIELD TIDAL CYCLES - JAN 30, 2016

MHHW

WAVE RUN UP

Changing every 6 hours, there are 2 high tides and 2 low tides every day. One high tide is higher than the other, called Higher High Water (HHW). And one low tide is lower than the other, called Lower Low Water (LLW).

The average of the higher high water height of each tidal day observed over the National Tidal Datum Epoch, which is a standard 19 year observation period.

Wave runup is the maximum vertical extent of wave uprush on a beach or structure above the still water level. Wave runup is an important process in causing and or promoting erosion.
