Groundwater
underground surface beneath which earth materials, as soil or rock, are saturated with water.
Infiltration
the act or process of infiltrating.
Aquifer
Conducting water
River basin
Area of land where all water flows over or under into a major river
Tributary

Watershed
An area where all water drains into the same place (there are smaller watersheds within the same river basin)
Runoff
Water draining on a slope
Meandering system
Depositing river
Upwelling
To well up
Sunlight zone (Photic zone)
