Open System
Is the river drainage basin system an OPEN or CLOSED system?
Channel flow: Water in streams
What does channel flow mean?
Water percolates into deep bedrock.
What does deep percolation mean?
Water loss by evaporation from the soil and by transpiration from plants.
What does evapotranspiration mean?
Water flowing through porous bedrock in the ground
What does ground water flow mean?
Any moisture from the sky - rain, snow, sleet, hail, dew.
What does precipitation mean?
Water infiltrates into the soil
What does soil infiltration mean?
Surface flow: water flowing over saturated fields
What does surface flow mean?
Water flowing through the soil
What does throughflow mean?
When the leaves on trees intercept the rainfall before it touches the ground.
What does vegetation interception mean?
Precipitation
