AQFR |
|
aquifer |
|
|
|
layer that contains and transmits significant volumes of groundwater
under ordinary hydraulic gradients |
|

UNC |
AQFR |
|
unconfined aquifer |
|
watertable aquifer |
aquifer with upper water surface vertically unconstrained and at atmospheric
pressure |

UNC |
|
|
perched aquifer |
|
saturated lens held by a localised impervious horizon within unsaturated
zone |
|

SUNC |
AQFR |
|
semi-unconfined aquifer |
|
|
a completely saturated aquifer that is bounded above by a semi-pervious
layer. Lowering of the head will generate a vertical flow from the
semi-pervious layer and horizontal flow in the semi-pervious layer
cannot be ignored |

SCA |
AQFR |
|
semi-confined aquifer |
|
leaky aquifer |
a completely saturated aquifer that is bounded above by a semi-pervious
layer. Lowering of the head will generate a vertical flow from the
semi-pervious layer with negligible horizontal flow in the semi-pervious
layer |

CONA |
AQFR |
|
confined aquifer |
|
|
completely saturated aquifer whose upper and lower boundaries are
impervious layers and water pressure is usually higher than atmospheric
so that the head is above the top of the aquifer |

semi-pervious layer |
layer with low though measurable hydraulic conductivity |

aquiclude |
|
|
impervious layer, impermeable layer |
layer that does not permit measurable transmission of water under
natural ordinary hydraulic gradients |
