Table 1 1 . — Mass transport, shallow-water waves 



(i<0.5)- 



-Continued 



The comparison of measured and theoretical values of mass trans- 

 port, at various depths below the water surface, is shown for several 

 representative waves in table 11. As in the case of deep-water waves, 

 the trochoidal theory does not admit the existence of mass transport; 

 the theoretical value given by the Stokes-Struik theory is:
