Plunge pool Plunge pool A plunge pool (or plunge basin or waterfall lake) is a deep depression in a stream bed at the base of a waterfall or shut-in. It is created by the erosional forces of cascading water on the rocks at formation's base where the water impacts. The term may refer to the water occupying the depression, or the depression itself. 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. Plunge pools are often very deep, generally related to the
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,
