Definition 



Surf zone approximation of P. 

 (eq. A-39) 



Deepwater P 



Passive earth force (eq. 7-145) 



Gage pressure; pressure at any 



distance below fluid surface 



relative to surface 



# Atmospheric pressure at point 

 located distance r from hurri- 

 cane storm center 



# Precipitation rate 



• Percentage of exceedance 

 (Fig. 7-41) 



Total or absolute subsurface 

 pressure--includes dynamic, 

 static, and atmospheric pressures 

 (eq. 2-26) 



Atmospheric pressure (eq. 2-26) 



Maximum dynamic pressure by 

 breaking and broken waves on 

 vertical wall (eq. 7-85) 



Maximum soil bearing pressure 

 beneath quay wall caisson after 

 backfilling 



Pressure at outskirts or periph- 

 ery of storm 



Central pressure of storm; CPI 



Maximum broken wave hydrostatic 

 pressure against wall (eq. 7-98) 



Nonbreaking wave pressure differ- 

 ence from still-water hydrostatic 

 pressure as clapotis crest or 

 trough passes (eq. 7-75) 



Hydrostatic pressure 



Overtopping rate
