36. Singamsetti and Wind (1980) collected laboratory data and combined 

 the results with data from Galvin (1969) and Iversen (1952). Singamsetti and 

 Wind found 



Ob = 0.575m - 031 



(28) 



valid for 0.02 < H /L < 0.065 and 1/40 < m < 1/5 , and 



7b = 0.568m 0107 



(29) 



valid for 0.02 < H /L o < 0.06 and 1/40 < m < 1/10 . 



37. Sunamura (1981) conducted a laboratory experiment and combined the 

 results with data from Iversen (1952); Bowen, Inman, and Simmons (1969); and 

 Goda (1970) to obtain the simple equation 



7b = Lift 



1/6 



(30) 



which can be written as 



7b = l.lm 1/e 



-1/12 



(31) 



38. Sunamura (1982) obtained the following empirical relation for fij, 

 using data collected from small-scale laboratory experiments (Sunamura and 

 Horikawa 1975) : 



fl b = 1.0m 02 



(32) 



Sunamura found good agreement between Equation 32 and prototype -scale 

 laboratory experiments (Kajima et al. 1983).
