the entire experiment series, and the profile depths used in this report are 

 an average of the three lines. 



174. The numbering of the CE cases is discussed by Kraus and Larson 

 (1988a) and essentially agrees with the system used by Hallermeier (1987). 

 Table 1 summarizes the CE cases which started from a plane slope of 1:15, 

 giving the wave and water level conditions. The deepwater wave steepness is 

 also listed and was calculated using linear wave theory. Two cases not given 

 in Table 1 were conducted from an initial profile that was irregular (Cases 

 510 and 610). Also, a repetition run was performed for Case 100 (Case 110), 

 and satisfactory agreement was achieved between the two cases (Saville 1957). 

 In Case 911 the water level varied stepwise in a sinusoidal manner, but the 

 wave and sand parameters were identical to those in Case 901. The period of 

 the water level variation was approximately 12 hr, the amplitude 0.45 m, and 

 the mean water level 3.96 m. 



175. The wave height was measured with a step resistance gage placed in 

 a fixed position at the toe of the beach during the experiments. The incident 

 wave was measured before any reflection occurred against the wave paddle. The 

 accuracy of the wave measurements was about 3 cm (0.1 ft), and the wave period 

 was quite accurately set due to the large stroke length of the wavemaker and 

 fixed gear ratio. For most of the cases the breaking wave height and breaker 

 location were estimated visually at specific times during a run. 



CRIEPI experiments 



176. The CRIEPI LWT is similar in size to the CE LWT, except that it is 

 somewhat narrower (205 x 3.4 x 6 m) . The experiment program consisted of 24 

 cases with wave periods ranging between 3.0 and 12.0 sec and generated wave 

 heights between 0.3 and 1.8 m. A summary of the CRIEPI cases is given in 

 Table 2, in which the numbering is identical to that used by Kajima et al . 

 (1983b). All CRIEPI cases were performed with monochromatic waves and fixed 

 water level. Many of the cases started from a plane beach slope (17 of the 

 24), but the initial slope was varied, ranging from 1:50 to 1:10 in individual 

 cases . 



177. As in the CE experiments, two different grain sizes were used, 

 0.27 mm and 0.47 mm. For the present study the CRIEPI profile survey was 

 digitized from charts enlarged from those given by Kajima et al . (1983b) with
