Surface Water

- is water collecting on the ground or in a river and lake;

it is related to water collecting as groundwater or atmospheric

water.

Surface water is naturally replenished by precipitation and

naturally lost through discharge to evaporation and sub-

surface into the ground. Although there are other sources of

groundwater, such as connate water and magmatic water,

precipitation is the major one and groundwater originated in this

way is called meteoric water.

Water on Earth is known by different terms, depending on where it

is and where it came from.  

Meteoric water -water is in circulation 

Juvenile water - water that comes from the interior of the earth

Connate water - "fossil" water, often saline

Surface water - water in rivers, lakes, oceans and so on

Groundwater - located beneath the ground surface

Lakes

A body of (usually fresh) water surrounded by land

Rivers

A large natural stream of water
