The wave lengths and celerities of small amplitude waves have been computed with the aid of a digital computer TOSBAC-3123 and compiled in four tables. The first and the third tables are concerned with prototype waves for the wave period of 2 to 30 seconds in the water of 0.2 to 300 meters deep. The second and the fourth tables are concerned with model waves for the wave period of 0.05 to 10 seconds in the water of 1 to 300 centimeters deep.
　In addition a design diagram is provided for the wave lengths and celerities of finite amplitude waves which have deen estimated with the aid of several wave theories.
