2. SURFACE WATER
Surface water is water on the surface of continents such as in a river,
lake, or wetland.
It can be contrasted with groundwater and atmospheric water.
3. REPLENISHING
Non-saline surface water uses is replenished by precipitation and by
recruitment from ground-water.
It is lost through evaporation, seepage into the ground where it becomes
ground-water, used by plants for transpiration, extracted by mankind for
agriculture, living, industry or discharged to the sea where it becomes
saline.
