Drainage Basins as Open Systems

Drainage Basins as Open Systems

1. Open System - A system containing inputs and outputs

   • Drainage Basins are open systems, as they contain a number of inputs and outputs.
     • Inputs: Precipitation
     • Outputs: Transpiration, Evaporation, Channel Flow

2. Closed System - A system that does not contain inputs or outputs. Instead, everything in the system will travel around the system indefinitely

   • The Water Cycle as a whole is a close system. This is because no water is created or leaves Earth.
