Water temperature, as a scientific topic, refers to the thermal state of water expressed typically in degrees Celsius or Kelvin and governed by molecular kinetic energy, heat capacity, and heat exchange processes. It is a fundamental physical parameter controlling chemical reaction rates, solubility of gases (e.g., oxygen, CO₂), density-driven stratification, and phase transitions. In aquatic systems, water temperature regulates biological metabolism, species distributions, and ecosystem processes, and is influenced by solar radiation, atmospheric conditions, mixing, and advective heat transport. Accurate measurement and modeling of water temperature are critical in hydrology, limnology, oceanography, climate science, and environmental monitoring.
As the frequency and intensity of heat waves increase across the U.S., a similar but more striking phenomenon is occurring in American rivers.
