 | Term | Definition |
| |
Aeration Zone |
where pore spaces in soil and rock contain air and water, and water is prevented from moving deeper by water tension |
| |
aquifer |
The name given to underground soil or rock through which water can flow through |
| |
depletion |
to decrease seriously or exhaust the abundance or supply of |
| |
discharge |
the water the that leaves an aquifer |
| |
drawndown |
a lowering of the ground water surface caused by pumping |
| |
flow rate |
the amount of fluid that flows in a given time |
| |
groundwater |
water that flows or seeps downward |
| |
Hydrologic Cycle |
the cyclic transfer of water vapor |
| |
impermeable layer |
a layer of solid material that doesn't allow water to seep through |
| |
infiltration |
flow of water from the land surface into the passage of liquid |
| |
monitoring well |
wells used to monitor the hydraulic head or sample the groundwater for chemical constituents |
| |
pore space/ porosity |
a measure of the water- bearing capacity of sub- surface rock |
| |
permeable/ permeability |
the ability of a material to allow the passage of liquid |
| |
recharge |
water added to an aquifer |
| |
saturation zone |
the subsurface layer in which groundwater seeps up from a water table by capillary action to fill pores |
| |
surface water |
water that is on Earth's surface |
| |
springs |
a point where groundwater flows out of the ground, and is thus where the aquifer surface meets the ground surface |
| |
water table |
the top of the water surface in the saturated part of an aquifer |
| |
well |
A pipe in the ground that fills with ground water |
| |
withdrawl |
water removed from a ground- or surface- water source for use |
