a = Maximum indentation (headland design) 



A = Empirical scale parameter that relates to the median 

 beach grain size 



A e = Erosion area of cross-sectional profile 



A t = Area of breakwater cross section 



b = Headland spacing 



B n = Bulk number, A/D^q 2 



C' = Effective slope "as built", A/h' c 2 



C b = Wave group speed at breaking 



d = Depth at structure 



d = Depth at gap between adjacent breakwater segment 



d s = Average water depth at the structure 



d sa = Depth at annual seaward limit of littoral zone 



D = Water depth (equilibrium profile) 



D 50 = Mean grain size of material in project area 



Dn50 = Nominal diameter, (W 50 /pJ 1/3 



g = Acceleration of gravity (9.81 m/sec 2 ) 



h = Water depth at toe of structure
