Watershed
A watershed is the frontier between two catchment areas.
This line divides the flow of surface water (springs, rainwater) into two different directions, each one corresponding to a distinct catchment area and outlet.
The watershed in France between the Mediterranean and Atlantic catchment areas: on the right, a drop of rain a drop of rain will find its way to the Atlantic, on the left, to the Mediterranean. © Guillaume Brialon CC by-nc-sa 2.0
