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 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
