See below itemized similarities and differences of surface and subsurface waters.
SURFACE WATER
Input: Through precipitation. When precipitation falls, its a runoff when it doesn't seep into the ground.
Output: Rivers or streams
Storage: Watersheds
SUBSURFACE WATER
Input: Precipitation through recharging process.
Output: When atmospheric pressure above ground is lower than subsurface water pressure it flows as rivers, streams and becomes a source of drinking water or irrigation water in farming.
Storage: Acquifers, rock layer that holds water.
