Study Notes

  • Water is the most important substance on Earth and the subject of hydrology
  • Hydrology is the science of studying water, specifically the distribution and movement of water on and below the Earth's surface, as well as the impact of human activity
  • The hydrologic cycle involves three major components: precipitation, evaporation, and condensation
  • Evaporation is the process of water turning into a gas, driving the water cycle
  • Condensation is the change of state from gas to liquid, forming clouds through condensation
  • Precipitation is any product of condensation that falls from clouds, including forms such as rain, snow, hail, and sleet
  • Infiltration is the process of water soaking into the soil
  • Transpiration is the process of water movement through a plant and its evaporation from aerial parts
  • Surface runoff occurs when there is more water than land can absorb
  • Storage involves the movement of water from one reservoir to another, including groundwater in aquifers
  • The water budget measures the inputs, outputs, and stores of water in a system and helps determine change in storage.
  • A lake example given with precipitation, inflow, outflow, and evaporation measurements to calculate water surface elevation change.
