What is the drainage basin as an open system?Show answer
The drainage basin is the local, open-system expression of the water cycle. Its single input is precipitation; its stores are interception (on vegetation), surface storage, soil moisture and groundwater; its flows (transfers) are infiltration, percolation, throughflow, overland flow (surface runoff), groundwater flow and channel flow; and its outputs are evapotranspiration and channel discharge at the basin mouth. The way precipitation is partitioned between these stores and flows determines how the river responds to rain.
