Kraus (1989); therefore, this method of determining bar size and location was 

 used in all tests. 

 Monochromatic wave tests 



114. Base tests consisted of various wave conditions and bar configura- 

 tions for which three parameters were varied: H /L , & 1 , and & 3 . The 

 tests involved five deepwater wave steepnesses, six seaward bar angles, and 

 four shoreward bar angles. Design variables are listed in Table 7.

115. Six tests were also conducted for a design value of deepwater wave 

 steepness (H /L = 0.05) for different combinations of wave height and period. 

 Bar configurations consisting of three seaward bar angles (5, 10, and 15 deg) 

 and one shoreward bar angle (20 deg) were subjected to two wave conditions
