snowmelt

This term functions as both a description of a natural process and a reference to the resulting liquid. It is primarily used in scientific, environmental, and geographical contexts to describe the transition of frozen precipitation into runoff. Unlike the general term "melting," which can apply to any substance, "snowmelt" is specific to the hydrological cycle.

As a mass noun, it describes an uncountable volume of water or a continuous seasonal event. It does not typically take a plural form because it refers to a collective phenomenon or a bulk quantity of water rather than individual units.
