97. It was also desirable to generate waves that did not separate into 

 multiple wave forms, or solitons, as discussed by Galvin (1970). Galvin 

 defines solitons as multiple waves that separate from individual waves pro- 

 duced by wave generators in shallow water, and formation of these nonlinear 

 waves is not restricted to any particular kind of equipment. Galvin suggests 

 solitons develop because the wave generator motion does not match the water 

 particle motion at the wave board. The wave conditions listed in Table 5 were 

 plotted on Figure 25 (Galvin 1970) to predict the wave form that would be
