kinematics of a short crested wave. 



A window near a crest of the short crested wave given in Fig. 5.27 has been com- 

 puted at orders 1 through 4. The results in that window are given in Fig. 5.28 through 

 5.35. Figures 5.28, 5.30, 5.32, 5.34 show the errors in the free surface boundary con- 

 ditions at each of the measured nodes. These are the data that would be analyzed in 

 a practical situation. Figs. 5.29, 5.31, 5.33, 5.35 give a comparison between the pre- 

 dicted and actual values for the water surface and the velocities at the surface at the
