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 the conserved nature of the functional regions and the precise change in the actual amino acid, the Sequence Feature Variant Type is defined. A sequence feature is basically a collection of amino acids within a protein, where the collection may be a continuous range or some discrete residues. Most sequence features are from experimental results, but there are some that are from computational analysis. For each sequence feature, the variations exist between many proteins from different related species. The variant types define the exact amino acid at each location for a feature. The larger the mutation at each location for
