Study Notes

Drainage Basins (Cuencas)

  • Drainage basins are areas of land that drain into a common body of water, like a river, lake, or ocean.
  • There are three types of drainage basins:
    • Exoreic: These basins drain water to an ocean. The rivers of the Buenos Aires and Patagonian regions flow to the Atlantic Ocean.
    • Endoreic: These basins drain water into inland bodies of water, like lakes, or they dry up. The water may remain in a lake or swamp.
    • Areic: These basins have water courses that disappear due to evaporation or infiltration.
