Table 2. — Deep-water waves ( y>0.5 j comparison of measured to theoretical 



velocity and length 



The measured values for the percentage of wave height above still 

 water level are tabulated in table 3. The results are presented 

 graphically in Figure 2, where the solid line represents the theoretical 

 values derived from Gaillard's (trochoidal theory) formula: 



^-0.5 + ^^

and the dotted line, the values derived from Levi-Civita's formula:
