Abstract
AIR is often entrained naturally by flowing water—for example, in the plunging waters of mountain streams, waterfalls, bores, breakers, hydraulic jumps and subterranean siphons—and, in these and similar situations, appears generally to be beneficial. The quality of the water, certainly, is improved by air entrainment and very few hazards tend to arise with these naturally occurring flows.
