Groundwater Terminology A- D
Help!

|

|---|---|---|---|---|---|
| show | The zone immediately below the land surface where the pores contain both water and air, but are not totally saturated with water. Plant roots can capture the moisture passing through this zone, but it cannot provide water for wells.
🗑
|
||||
| Aquiclude | show 🗑
|
||||
| show | An underground geological formation able to store and yield water.
🗑
|
||||
| Aquifer storage and retrieval (ASR | show 🗑
|
||||
| show | exist where the groundwater is bounded between layers of impermeable substances like clay or dense rock. When tapped by a well, water in confined aquifers is forced up, sometimes above the soil surface. This is how a flowing artesian well is formed.
🗑
|
||||
| show | Putting water back into groundwater storage from surface water supplies such as irrigation, or induced infiltration from streams or wells. Includes aquifer storage and retrieval (ASR).
🗑
|
||||
| Baseflow | show 🗑
|
||||
| Best management practices (BMP’s) | show 🗑
|
||||
| Brackish | show 🗑
|
||||
| show | Capillary water moves upward from the water table in the aeration zone by capillary action. This water can move slowly and in any direction. While most plants rely on water from precipitation in the unsaturated zone, their roots may tap into capillary h20

| Collection site | show 🗑
|
||||
| Condensation | show 🗑
|
||||
| Cone of depression | show 🗑
|
||||
| Confined aquifer | show 🗑
|
||||
| Confining layer | show 🗑
|
||||
| Conservation | show 🗑
|
||||
| Consolidated rock | show 🗑
|
||||
| show | Reducing the water supply (i.e., removing water from a river, lake or aquifer) without returning an equal amount. Examples include water intake by plants, humans, and other animals and the incorporation of water into industrial or food products.
🗑
|
||||
| Contaminant | show 🗑
|
||||
| show | Groundwater movement equation developed by Henry Darcy in the mid-1800’s.
🗑
|
||||
| show | The loss of water from surface water reservoirs or groundwater aquifers at a rate greater than that of recharge.
🗑
|
||||
| Diffusion | show 🗑
|
||||
| show | An outflow of water from a stream, pipe, groundwater aquifer, or watershed; the opposite of recharge.
🗑
|
||||
| show | The area or zone where groundwater emerges from the aquifer. The outflow maybe into a stream, lake, spring, wetland, etc.
🗑
|
||||
| show | A lowering of the groundwater level caused by pumping.
🗑
|
||||
| show | An extended period with little or no precipitation; often affects crop production and availability of water supplies.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
