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
Sequence feature variant type a feature, the larger its number of variant types. For a given protein, once its amino acid sequence is determined, its sequence feature variant type is determined. SFVTs can be used to study the protein functions across many related species. Such studies have been carried out on several human pathogens. SFVTs are also available on Influenza Research Database for flu proteins and on Virus Pathogen Database and Analysis Resource for Dengue virus. Sequence feature variant type The Sequence Feature Variant Type (SFVT) refers to the defined sequence variation (mutation) of a given sequence feature in a protein. Consider a protein,
