Term | Definition |
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 |
Condensation | A gas that turns to a liquid |
Soil | the upper layer of earth in which plants grow |
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. |
