Figure 3-8. Theoretical and observed relationship between height and stan- 

 dard deviation of sea-surface elevations as a function of 

 relative water depth. (Dashed curves represent the stream- 

 function wave theory (Dean, 1974). The solid curve represents 

 the upper limit of short-term measurements from two field 

 experiments (Thompson and Seelig, 1984; Hotta and Mizuguchi, 

 1980).)
