SYMBOLS AND DEFINITIONS 



a' volume concentration, ratio of volume of solids to total volume 

 in a sand deposit (defined by eq. 8), dimensionless 



e void ratio, ratio of volume of voids to volume of solids in a sand 

 deposit (defined by eq. 7), dimensionless 



G specific gravity (defined by eq. 6) , dimensionless 



1^ immersed weight rate of longshore transport (defined by eq. 5) , 

 pounds of sand (weighed under water) per year 



K constant of proportionality in energy flux method (defined by 

 eq. 1) , cubic yards-seconds per pound-year 



P^ s the energy flux factor, foot-pounds per second per foot 



Q volume rate of longshore transport, cubic yards per year 



Y unit weight of sand (defined by eq. 10), pounds per cubic foot 



Y s unit weight of solids in sand, pounds per cubic foot 



Y' submerged unit weight of solids (defined by eq. 4), pounds per cubic 

 foot 



Y w unit weight of distilled water, pounds per cubic foot 



Y unit weight of water in which sand is immersed, pounds per cubic 

 foot 



NOTE. --The dimensionless immersed weight coefficient (Longuet and 

 Higgins, 1972, p. 211), using the definitions above, equals the term 

 in parenthesis in equation (5) , multiplied by 2 to account for the use 

 of significant height in P^g, and divided by 31.536 x 10 6 , the number 

 of seconds in a year.
