Abstract

It has long been known that the study of wind-generated waves on a water surface is difficult in the laboratory because of the large "fetch," or distance downwind, needed for the growth of waves large enough to behave as gravity waves rather than capillary ripples. Johnson (1948), on the evidence of experiments by Stanton et al. (1932) and those of his own at Clear Lake, California, concludes that a channel 311 feet long with a windspeed of 4.5 feet/sec. would reproduce the prototype conditions of a 10 mile fetch with a 40 m. p. h. wind....
