Plunge pool height of fall, the volume of water, the resistance of the rock below the pool and other factors. The impacting and swirling water, sometimes carrying rocks within it, abrades the riverbed into a basin, which often features rough and irregular sides. Plunge pools can remain long after the waterfall has ceased flow or the stream has been diverted. Several examples of former plunge pools exist at Dry Falls in the Channeled Scablands of eastern Washington. Plunge pools are fluvial features of erosion which occur in the youthful stage of river development, characterized by steeper gradients and faster water flows. Where
Plunge dip Plunge dip A plunge dip (or simply, a dip) is a bath designed to immerse livestock in liquid pesticide or other treatment. Typically a dip is designed as a narrow channel (about the width of the animal) through which the animals walks along through into progressively deeper liquid until the animal is immersed (apart from its head so it can breathe) and then becomes progressively shallower until the animal exits the channel. As many animals can be walking through the channel one after another, it is an efficient method of delivering pesticide or other liquid treatments to a large herd.
