| Groundwater Discharge | The volumetric flow rate of groundwater through an aquifer |
| Groundwater Recharge | The process where water moves downward from surface water to groundwater |
| Confined Aquifer | is an aquifer below the land surface that is saturated with water. Layers of impermeable material are both above and below the aquifer, causing it to be under pressure |
| Unconfined Aquifer | A groundwater aquifer is said to be unconfined when its upper surface (water table) is open to the atmosphere through permeable material. |
| Artesian well | a well in which water is under pressure,one in which the water flows to the surface naturally |
| Water table | the level below which the ground is saturated with water. |
| Water table well | A well that goes into the water table. |
| Infiltration | The process in which surface water enters the soil. |
| Percolation | The process of liquid passing trough a filter |
| Evaporation | A liquid that turns to a gas |

| Watershed/ drainage basin | Image result for Watershed/ drainage basin definition Drainage basin, also called Catchment Area, or (in North America) Watershed, area from which all precipitation flows to a single stream or set of streams. |
| Divide | A line on a water table on either side of which the water table slopes downward. It is analogous to a drainage divide between two drainage basins on a land surface. |
| Intermittent stream | normally cease flowing for weeks or months each year |
| Ephemeral stream | a stream that flows only briefly during and following a period of rainfall in the immediate locality. |
| Uplands | An area of high or hilly land. |
| Stream order | Is a measure of related size of streams. |
| Riparian Vegetation | A riparian zone or riparian area is the interface between land and a river or stream |
| Transpiration | Transpiration is the process where plants absorb water through the roots and then give off water vapour through the pores in their leaves. |
| Precipitation | rain, snow, sleet, or hail that falls to the ground. |
