Before revision: Dictionary of Geological Terms: Third Edition, p. 391, American Geological Institute (1984) Formation Plunge pools are formed by the natural force of falling water, such as at a waterfall or cascade; they also result from man-made structures such as some spillway designs.The Management of the Zambezi River Basin and Kariba Dam, p. 105 (2010) Plunge pools are often very deep, generally related to the height of fall, the volume of water, the resistance of the rock below the pool and other factors.Vincent J. Zipparro, Hans Hasen, Davis' Handbook of Applied Hydraulics, p. 16.46 (1993) The impacting and swirling water, sometimes carrying rocks within it, abrades the riverbed into a basin, which often features rough and irregular sides.
